I buy M. G. Chemicals products. I use their 600 series pos.
presensitized boards. They are not the cheapest. I buy the M.G.
Chemicals thru Circuit Specialists @ www.webtronics.com They also
have some other brand pos. presensitized boards that are cheaper but
I have not tried them out yet. Not many places selling the pos.
presensitized boards now days, or neg. boards for that matter now
that Kepro has gone out of business. Never tried ebay, they seem to
be bare boards and normally smaller sized than I want.
Never had good results doing the pos. resist myself and was a big
hassle to do it. I only do the pos. photo method myself using
presensitized boards, get much better results than I did with toner
transfer and once you are setup to do it really does not take that
long. You do need a good inkjet to print transparencies, I
currently use a HP CP 1700 with good results on HP transparencies.
The only thing I have a complaint on the M.G. Chemicals boards is
that sometimes they are cut sized to mm and sometimes to inches so I
try to figure on them being sized to the mm as they are slightly
smaller.
