This isn't really what OP asked for, but I've attached an excel sheet of some information I skimmed from running a python file I sloppily threw together (which is zipped up so I could upload it too). I put a recommended search term column together for googling to try to get a cost estimate that's just the supplier + part number.

Definitely not perfect, but hopefully useful to someone. And maybe someone that has more time than I do right now can modify my script to get a cost for parts that it's feasible (andymark) and generate a $/credit column too...
