I wouldnt go for Peachy yet,

Well if you have to much money and wanna sponser a great idea sure,
But imo its still way to low res and doesnt look like its great atm,

But ye Its a great concept and it might evolve as you can now look at Darwin and look what we've got now.

Imo get a Prusa i3 or Solidoodle,

If you go with Prusa i3 i would go with www.makerfarm.com,

It has great instructions and a great support that realy helps you,
The instructions are made with Videos, so someone is actualy making it step on step together with you.

I hope you will find the best printer fitting you ^^
