Hi
I've build one out of a old Y/X table. The machine is made out of junk i have had lying around except the Geko drive's for motor controllers. It's is a bit rough around the edges but works well. I find it is faster to manually drill a one off small PCB but if doing more than is is faster to use the mill. One thing that is great is you can engrave your enclosures with lettering and hardware mounts. I try and keep the components drill holes the same as much as i can because it is a pain to change the drills quickly. Also spend some time building a Vacuum table to hold your boards down.
I can send you a Picture or two if you want to have a look.
Cheers
Snow
