So far my experiences with CL have been positive. I built most of a bike using allofcraigslist.com, everyone was ok with shipping stuff to me. I didnt even use paypal once, though my only gripe was a 3TTT stem I bought was miss represented as a different model. I still got a fair price for the stem, though it did have some cosmetic damage that was not shown well in the picture. Though picking up a set of barely used Ultegra 6600 sl brakes for 50 bucks made up for it.
