^^^ I agree mostly, except that ebay is a really cheap way to get old moderate quality frames/bikes. Nobody wants to pay to ship a straight gauge chromoly frame, but if it's local you can get it for a song. Schwinn World Sports like the one someone posted earlier this week go for like 10 bucks. If any of these were local, they'd be a bargain.
