Homebrew PCBs

Hi all, maybe someone point me in a good direction here.  I am 
looking for a CNC / Milling machine to mill my own prototype PCB's 
with.  As more and more of my prototypes are SMT's, this now seems as 
a wise investment.  As I am not doing anything in production like 
quantities, just my own design/prototyping, these things can cost 
into insane amounts.

I have seen kits, and pricing ranging from $500 and up for various 
machines.

What I am wondering, does anyone have 1st hand experience with a 
desktop CNC/Milling machine I cause for my prototyping of SMT boards 
with, at a reasonable price.  $4,000 to me is just way to expensive 
for a hobbyist, though something over or around $1,000 is something I 
would consider.

Look forward to getting some feedback, and hopefully a milling 
machine very soon !!

Thanks
