As I'm working on this project (a lot slower than I'd like), I've started a list of the parts I am thinking of using and their prices. I'm looking at what it would take to order 1000 of these if it can git far enough. It might be a bit un-ordered right now, but it will eventually make it to the official BOM list on this site (that's what I've used so far).

The list is here: Bill Of Materials
