I have been working on stripping the arduino down to something that should cost about $6 by pulling the power and the serial off of the board.
The pic above is a dip version. If I went to olimex I could probably get the board cost to about 6 bucks for the board. So I thought about smt and eliminating the headers (which cost about a buck all told) This is where I am heading but it is not quite done.
