I realized the other day that I have enough spare parts to make an entire bike, if I only had a frame. I was going to get a super-cheap frame and build it up, really just for the heck of it. Could be a fun rain bike or maybe give it to a friend who's just getting into cycling.

I don't want to get a nice frame because the parts are all old, worn, low-end components. I was thinking of the $99 Performance or Nashbar frames, or a Motobecane from eBay. Anyone have experience with these frames? Is there any difference?
