I know a guy who owns a big electronics recycling outfit in the DC area. He pulls the circuit boards for anything that can't be reused and they get sent to other outfits who strip them for whatever precious metals they contain. I could find the name of whatever company that is, and if they don't ruin the boards they use, maybe they would ship you a box of them? I'm sure they normally throw them out afterwards because they're worthless...
