Homebrew PCBs

I have to admit, the EDM process sounds very interesting.  I am 99% 
certain it could be easily adapted to any existing CNC router (or 
mill).  My fear is the power supply - I don't know enough yet about 
the electronics to make the power supply.  By chance, do you have 
that link to the information you and the other fellow were talking 
about a couple of days ago?  I guess I should look that over to see 
if it is basic enough for me to understand it.
