But yeah... you have to deal with exposure time, chemicals etc... but it's working really well. I did many successful prototype PCB using fine pitch SMD components, i can't confirm if the toner method would work as this well. But as long as it's working for you... life is good

If you mess the toner transfer, what happen? is this easy to remove? What is the aprox cost of a toner-transfer sheet?

Films can be reuse again and again.
I didn't realize you were using the pre-sensitized boards. I tried that too... used a couple of 15w flourescent bulbs for exposure (not even close to the right equipment to be sure), couldn't really get the hang of it. I suppose it was because of those bulbs I used.
Toner Transfer Sheets $ - they weren't cheap, cheaper than presensitized boards, but a guy still has to buy the blank copper. If you screw up the toner, sure you can take it off with a steel wool pad, but then you have to start over again, transfer it somehow, blah blah blah.
I'd really love to get my hands on one of those Protomat S62's for the house...only $25K with the options...pocket change! NOT!
