An order of 20lb of copper clad PCB arrived, getting me closer to my goal of having the workshop stocked well enough so that I can build and experiment without triggering that "can't use it because I'm running low" instinct.
This is my second order from Copper Clad Laminates on ebay, and so far I've been pretty pleased with the product. This was one of his bulk items containing boards that maybe aren't the right size, have some light scratches or other imperfections that wouldn't qualify them for a regular batch, but are more than suitable for my purposes. It's all double sided and there's a nice variety of sizes too. At $1.05/lb, it's a pretty good deal.
