Craigs List in a hot market is just about a waste of time. Get to the yard sales super early, hit the garage sales that don't list bikes. Be prepared to spend the better part of a day going to garage sales. Repeat for a few/several weeks. You'll find some. Don't worry if it fits or not, keep trading up and then use the proceeds to buy the bike of your dreams, even if you have to pay full market for it.
