Woohoo C. Cecil!! You rock! 
Funded *and* sold out!
If everyone pays, then the refund when all the dust settles should be at least a dollar per PCB, which puts Yzr1 on target for three, and the total for the group buy at exactly 30! Perfect!
Check your email for details and instructions!
Edit: Changed "sold" to "claimed"

Check over that parts list -- I'm not sure it's completely accurate, and it may include stuff you don't need or already have (e.g. resistors, led, headers, or even the FTDI/USB if you already have an FTDI cable).
As an example, the project lists 7 of the 4-poin headers, while one of them should have been replaced by the double-header for the Z axis. (Incidentally, even 6 of the 4-pin connectors at $1.02 costs more than 10 of them at $0.84 because of the price break at 10.
)
I ended up getting the cost down quite a bit when I took out the stuff I already had...

Thank you all for a successful group buy!
Your PCBs were shipped out this morning via first class US mail, and you should receive them soon.
Here are the final per-PCB prices that everyone ended up getting. This is over $1 off of the originally estimated price per PCB!
The extras are going toward a school build and some freebies: [www.thefrankes.com]

A couple of people have noticed this, and one of you suggested that I alert the group, which made a lot of sense. There's nothing wrong -- it's just something to be aware of:
If you look closely at the circuit board where the FTDI chip goes, you'll notice a tiny solder bridge between pins 25 and 26 (below the "L" in "FT232RL"). I noticed it when I first inspected the board, and I looked at the original gerber files to make sure it was part of the design. It is, in fact, part of the original design (see photo below), so there's no need to try to remove it. (To confuse the issue, the instructions even say to look for things like this.)
If you did remove it, that's okay, too -- those pins (which both go to ground) are still connected inside of the outline of the chip.
One other thing to note is that the pin headers along the top of the board sit a little further in than those along the other sides. This is also exactly as it is in the original gerber files, but it means that the PCB might prevent some right-angle headers (like those in the Mouser project kit) from plugging all the way in unless the male headers are soldered a little high. (See the second photo.) This is probably more of an aesthetic issue than a functional one, but if you want to make sure they plug in completely, you can use one of the female connectors to space it properly when you solder it on.
