Homebrew PCBs

Jan,

Check out the group links section. Markus Zingg has a VERY nice 
setup... (Worth re-creating, IMO) Down side is that he uses Bungard 
chemicals, which are not cheap to get started with. But for a 
dedicated amateur, the prices weren't TOO bad, IMO. Bungard has a USA 
rep in the northwest (chems come from Canada) I made a phone call to 
get pricing.

Another member is successfully using the blackhole technique. (I 
apologise forgetting his name just now; especially as he was very 
helpful in several private emails awhile back. Can't look it up as 
I'm not on my "normal" computer!) 

Anyways, he uses a combination of thinktink and caswell off-the-shelf 
products. He's doing small production, and reports good results.

Hope this helps,

Ballendo
