26" SS parts buying.

Got hold of an old steel mountain bike frame (free) which I'm going to make in to a cheap singlespeed as a local runabout with flats rather than having to wear shoes with cleats all the time. And because I want to be like the cool kids. 8) 
Anyway, what are the best (read:cheapest) online shops to pick up parts? Will be needing new bearings, chainset/sprockets and wheels. All 26" stuff. Thanks for any help/guidance in where to look.
