For those of you that etch you own PCB’s, -have you tried this method?http://en.electroni-city.com/It looks promising.
Seems to provide some fine trace resolution. Needs some additional mechanical and toxicological care w/ handling the vynil but nothing too unreasonable (although personally I have an issue with ventilation :/ ). Furthermore, it reminded me that I have to delve into studying some tin plating option :) [currently resorting to post-soldering crude nail polish protection :x ]
Overall, thanks for the heads up :)
