WTB - Cheep trainer bike - small frame

Howdy

Anybody have a 50-52 cm bike/frame/partabuild you want to let go for a song? Old Schwinn Varsity collecting dust in the shed? Doesn't need to be pretty at all, or even fully functioning, as I'm a decent wrench... but it needs to be able to be made functioning easily and/or cheaply. No damaged frames, please.

Thanks!
