One of the Marines in my shop just bought a very nice Trek at a pawn shop. We looked at it online and it was going for about a grand. He got his for $150 and it has very little wear. He brought it to a local bike shop (there are tons here since just about everyone rides around here) and had them look it over and give it a tune up for $40. They replaced a small part and said it is as good as new. $190 for a good bike makes checking the pawn shops a worth while alternative.
