never tried photo etching myself... paid others to do it, but my work has always been
simpler in nature therefore the "radio shack" or equivilent kits have been good enough,
using three trays (acid, base, and water wash), sorta like photography :)

Can you enlighten me a little bit?  I'd love to investigate this avenue more.
