My question is what are the things one looks for in a photo resist ?

dyed ?
positive ?
cost ? availability ?

What is available in the States at a reasonable cost ? and is that
better then buying pre-coated boards ?

Dave

There was a gentleman on here that offered me coated boards last
year, but never offered prices.

I am still mechanically etching, but after seeing that T-Tech go on E-
bay for $$$$ I may sell mine and buy Ballendos unit.
