That SMT board looks sharp! Now I need to invest in a laser printer.

I got a used HP1012 from a friend with the speicific excuse to myself that I should get it so I could make my own PCBs. but its a great little printer for personal use. I didnt realize how little I needed color. My inkjet has been 'out of ink' (stupid chipped cartriges...) for probably 6 months now. I have spares away in drawers, just never needed to use it yet.

Where do you guys typically get your etching chemicals? And what is the typical cost?

Steve,
chemicals are dirt cheap, a 1kg bag for $5 will last you a long time, unless you run a professioal PCB business.
In Europe you can get ferric cloride and Sodium persulphate from the electronics suppliers that also sell componentes, so I would try radio shack or DigiKey.

I think I got my can of persulfate from webtronics I also picked up some flux while I was there, one of the best spent $2 in my life.
