I looked at the 20 largest metro areas Craig's List. April/May of 2009 there were several available. Thanks to this forum and the integrity of Dwight (the guy in Nashville from whom I bought the bike) I had a great experience. Bike was in beautiful condition (1996 with 42,000 miles) and was also British Racing Green, the fastest color.
Drove it home in mid-July and now it's got 47,000 miles on it. I have an ambitious maintenance plan for the winter but I'll be on it until ice blesses our roads.
Send me a personal email if you want more details about how I did this transaction. It might sound scary or risky but lots of us purchase bikes from far away (the further the better) and then drive them home.
