and so said I should forward it on...

I built a small one myself in order to build my mini clone.... I had
like 20 single sided boards to do, and I hate the non-professional
quality of etching based approaches (at least for me), so I decided to
build one.  It took a few days, and maybe a week or two of fooling
around to get it perfect, a few retries on dremel bits, but eventually
I ended up with something that can produce pretty professional (albeit
spartan - no silkscreen for example) pcbs.  My only complaint (other
than speed... you can never get enough speed) is that I've never been
able to get a dremel with good enough bearings and an end mill at the
right contour to get traces any narrower than .032 inches, which is
usable, but not ideal.

You can read about my cnc build (started back in February) in the
middle of my minimoog clone blog
