Take a look at RepRap-Fab.

what parts are failing? I have been through the same experience. The hot end is the most error prone and critical component. The filament drives usually work well and when they don't it's still due to something in the hot end.
I have 2 hot ends that are the adrians stepper-hot end v4 design which I think are a really good design. One of them works reliably the other one is untested.
I'm currently running the arcol.hu v3 hot end which I think is the best one I've run across including all the Makerbot versions. The only criticism I've heard about it is that people say it's over-engineered, fine by me... I was sick of the hot end issues.
both designs are excellent, but can be difficult to get. My tested version of the adrians v4 is from bryan reif* he doesn't actively make and sell them though. The other one is from mendel-parts.com and they have extreme delays. I think my delay was a little over 1 month. the arcol.hu one you need to order from their site, contact laszlo to find out when he's making another batch.
One other thing to take note of is the x cairrage... the adrians v4 hot end peek block will only go in one way, on a wades filament drive it's perpendicular. For the arcol.hu v3 hot end it fits well in a Prusa Mendel but won't fit at all in the standard mendel x carraige without some serious tweaking and replacing of parts.
I hope that helps some... if you are evaluating other solutions I have a few tips:
1. Stay away from designs that rely on PTFE threads for any structural integrity.
2. Don't mess with nichrome wire.
3. You want to heat as low as possible and keep the filament cool as low as possible.
4. pay attention to cable management, the arcol.hu is the only one I've seen that considered this in the design.

Everything fails. It drives me crazy. The hotend and the extruder drive itself.
Arcol seems nice altough that lasercut wood makes me nervous. I've seen a makerbot and it's ripped wood problems.
What about extruders? I have a friend with an up that can print me accurate stuff but I have a wade variant right now and the thing is nothing but trouble. I'm pretty sure it's my fault but for the life of me I can't figure out what I did wrong and I'm tired
What about the makergear stuff? Is that any good? It's cheap enough to ship to europe.

I can sugjest Makergear stuff. How did you mange to mess up a wades? Did you not hob your bolt right?

I suggest getting a hold of the Adrians v4 hot end. The best way to connect that hot end will be to an adrians extruder block, but that part isn't AS important.
The Makergear stuff is good quality on a design that has been around for a while and people consider mature. I'm sure Rick from Makergear would be happy to work with you.
I personally think the Adrians v4 hot end has several improvements over that design and is more likely to be successful. I don;t know of any real criticisms people have on that design, they just thing the complexity is unnecessary.
