You could always buy one then tell us what it is like 
ETA:
That was the Rapidbot Mega, actually a different printer now apparently discontinued.

Oh, I thought mega bot was launched in October based on their twitter feed

Hi Guys, I email MakeMendel questioning them about all the negative reviews about their products I could find online, and this is what they came up with. Still going for the demo on Monday, But not sure what to expect anymore... I mean why should I have to do the extra work to get the heated bed up to temprature, and why is this something they aren't doing themselves? Just one of the questions I intend on asking them... Anyone have any inputs? I really want to buy this printer, but I also don't want to land up with a white elephant... So please arm me with questions to help me get a better idea of what I'm getting into... Thanks 
Hi Hansveer,
Below are our comments.

Known issues : -
Q) Heated bed temperature very low - "The "heated" bed only gets up to 45c and this is after warming for a half hour or so. I cant print ABS on it or it warps really bad. I contacted makemendel and they told me to cut the wires and wire it directly to the power supply..."
"The heated print bed kind of pisses me off. Its false advertising to say the printer prints abs because it has a heated print bed when the print bed only gets to 35-45c. Bait and switch..."
A) With PLA you do not need to heat your Printbed. You can use Glass for PLA print.
For ABS, Use PCB Heatbed and give direct supply of 12 V to PCB.
Find below attached files which will help you in connection of 3 PCB to ATX and Printrboard.
Q) Filament Jamming - "my filament kept jamming and that the z-motor was kind of skipping on the filament eating it away as it would not enter the hotend.
My solution was to ad an extra the spring to press the filament firmly to the teeth of the feedwheel...."
A) This issue occurs if your Printbed is not leveled properly. It should be all linear while printing.
Nozzle tip and Printbed should have space to allow material to come out. If this distance is not kept proper either print will not stick to Printbed or Hotend will jam.
To resolve jamming, you can follow below steps.
Set Extruder Temperature to 230 degree and Extrude the clog material using Extrude command in Pronterface.
OR If that is not working then use some small rod which can go easily in Hotend, with the help of that push the clog material out.
Q) Head Jumping every 10-15 layers giving print errors - "An other thing I was wondering if anyone has experience with: I just printed a vertical testshaft, round, 11mm diameter. 2 cm high with 0.1mm layers. I noticed that every 10 to 15 layers the x or y position of the head jumps about 0.02mm . it gives a small error in the print. the funny thing is that it corrects itself over the period of 5 to 10 layers. and eventually lines out again. this whole thing repeats over the whole Z-length of the print.
On average the print is within limits. it just gives an less pleasing finish on the side of the print."
A) This happens if your stl file is having some issue.
Q) Head cooling issues -
A) Kindly describe your point briefly.
Q) Instruction manual not comprehensive
A) We are working to improve our manual . We have New Wiki page for all our machines, where building information if given and we are trying to improve it.
A video Manual is also available. Here : [www.youtube.com]-
Q) No way to level print bed - "There isnt any good way to level the print bed. Actually you cant level the bed at all. To level the X axis I have to manually turn one stepper motor on the Z axis untill I level the X axis on the print bed. The Y axis cannot be leveled at all so hope yours is level when you get it or put it together."
A) To level Printbed, You need to make sure that all your nuts and bearings are equally loose, as entire Printbed is leveled on 6 vertical rods.
By rotating Z couplings you can level your Printbed.
Q) Mac Support?
A) Currently our machine does not support Mac.
Q) Printing temperature too low to print ABS.
A) It can be increase by giving direct 12 V supply to all PCB Heatbed. Printrboard can handle upto 12 V, which gets distributed among Motors, PCB, Hotend.
9) Power Supply mounted improperly (rapidbot 3.0) - "My one huge complaint, the power supply isnt mounted correctly and the screws they used to mount it are not the right size so they work their way out with multiple times plugging and unplugging the power cable. They over used masking tape, they used it for EVERYTHING, that and zip ties. The printrboard is mounted with zipties on the botom of the machine. The power supply is in the same regeon. All of the cables for the power supply are covered in masking tape holding them in place, not a very elagant solution but it works. Some of the vents on the PSU were covered with masking tape, i had to cut it away so it could breath properly."
A) We have modified design for better placement of Power supply. The cables which are not in use are sealed with paper tape.

Hi psych0hans,
I have recently purchased MegaBot from Makemendel, It was just amazing. they delivered me the machine within 1 week, I also assembled the same, Earlier I had some calibration issues after talking to their support team I am no more having any issues Its just working smoothly with the PLA and gives a good output.
I would recommend MegaBot from Makemendel. Their support is good
Thanks...

I have a very hard time believing this. Just a couple of days ago Tejal from Makemendel posted this [forums.reprap.org] which shows a medium size print from a megabot to show the quality of the print and I have to say it looks like something I would throw right into the recycling bin. The part looks like it has under extrusion problems and possibly over heated PLA trying to get it to extrude correctly. It looks fragile as a result and does not look like it is capable of producing structurally usable parts.

Well all I can say about make-mendel is crap. Order something from them, they desptach to other addresses and then they accuse people of telling lies. Also, they do local fabrication of stuff with outdated tools with no regards to geometry or basic engineering. There super flawed hot end is one such example. To top bad quality, they have veen .worse customer service. All in all, they are just trying to sell dung to people in the name of cheap prices. Just see what kind of pictures they post of the prints. Even an un caliberated mendel will not produce such atrocious prints...
