There are still some deals in urban environs.

I got the Peugeot Orient Express for $20 at a garage sale in north Orange County back in May of 2009. Yes, I spent some money on it after I got it, but it's a great bike, and I still ride it every week.

I got this one for $130 from the classified advertisements at a local university. It is a 1983 SR Semi Pro, and it's also a great bike.
Both of these were bought in Orange County.
