Not the deal of the century, or even year, but i'm pretty happy with my Trek TX500, from '76 or '77, that ran me $100 and included a trainer. I've put a basic tune, tires and bar tape on so far, along with a good cleaning. It runs like a dream, not really that tempted to upgrade anything at all! As long as I stay off any newer bikes, this one's going to be all i need...
