I dont have a source for circuit board material, but if you're interested in trying polycarbonate instead try onlinemetals.com. I bought .06 inch thick (which is about 1/16th inch if my math's right...) clear polycarbonate sheets cut into 1 sq ft pieces from them in January. They were 2 bucks a sheet plus another small cut fee. The sheets have a thin, peel able plastic wrap on both sides. Outside of lips, also take a look at their 'carbon steel balls grade 1000'----been using them for ballast weights rather than lead. Really cheap.
