I was thinking of the pins that I found at MarcoSpecialties, and also Gravitech.us (shorter legs).
Something like $1.90 for 20 pins, or maybe 32. I have used a lot of them as sockets for promini's with "interconnect" pins added as the promini leads (also from gravitech.us).
One-chip Arduino - the Solarbotic Ardweeny, with the components mounted on a board installed on the chips back.
