Homebrew PCBs

Well, let's see here.  You are asking a group of people to commit to 
purchasing a machine based on a description that would barely 
describe a piece of paper.

If you actually wanted to sell something, why not provide some 
tangible information and photos...

Servos or steppers
Drives included or not
Ball screws, acme screws, or belt drives
Way system used
Spindle HP
Spindle drive
Variable speed or constant speed speed
Type of spindle control
Quick change tools, Collets, chuck?
C-Frame, bridge, or gantry machine?

What else does a person need to utilize this machine?  Computer, 
software, power supplies, etc...

How fast is this machine?  Can you provide any examples of how fast 
it can mill isolation grooves on a given size board?

Why don't you just provide some photographs and real details of 
these machines?  I get hundreds of spam emails everyday asking me to 
provide financial information to purchase "something", at least they 
provide SOME details!
