I'd buy them and donate them to the Topeka Cycle Project. (my old home town) I took a rubbermaid tub full of used parts down there. They build bikes and give 'em away. They sell a few...only enough to cover the rent. All tools were donated. They pull bikes out of the dump, dumpsters, whatever. Strip'em down, clean them up.

If you put in 20hrs of time, you can build yourself a bike to take home.
