Oh, and thanks again. Seeing that ZIF socket gave me an idea about how to breadboard several of the surface mount to DIP/SIP adapters I have very quickly. I could put a 40-48 position ZIF on a protoboard with each position going to a wire-wrap header and stack up as many components as will fit in the socket, then wire-wrap to my Arduino header pins. Since the ZIF socket doesn't care how wide the parts are I can mix and match through hole and SMDs on adapters.
