I would find the deal first, look for a good steel lugged frame, pull the seat post to inspect for internal rust. I found an older (1987) steel Trek at Salvation Army for $18. I also found a 1993 Schwinn Criss Cross with Chrome Moly frame at a yard sale for $10. The problem with Thrift stores and garage sales is that they are hit or miss at best.
Be sure to get one with 700 wheels. The more flexible you are on brand and model, the more deals you are going to find.
