Homebrew PCBs

I suspect one could build a CO2 at 20 - 80 watts for the $500 price range.

A 2 watt green laser might have somewhat interesting characteristics.  
It would be slow enough to perhaps be easier to control.  Green PCB 
fiberglass might not be cut quite as easily by a green laser.

However, I agree, a mill seems to be a much better way to go.  I'd not 
want to be anywhere around a CO2 laser aimed at shiny copper.
