I happen to think finding a good quality steel frame from past days and restoring it into a functioning bike is really fun. I don't have any dumpster finds, but my girlfriends mom gave me 1982 Fuji Team that was quite rusty, none of the components worked, and the wheels were beyond repair. I had a grand old time fixing it up, building it some new wheels, and setting it up as a fixed gear. If somebody has a good time finding an old frame somewhere (anywhere) and turning it into a functioning machine, then god bless them because they are havning fun doing it. It also puts another bike on the road, which is good for bikers everywhere.

I also restored a workshop built Raleigh back to its original condition. People like myself into high end vintage bikes also look around when they pass a yard sale or thrift shop, because you never know what you'll find. Peugeot PX-10 can look like UO/UE-10 under thick grime. same said for Schwinn Paramounts.

Fixed gear riding is definately a fad, but it is a fad because it's fun. If your doing it because its "cool" and find out you really like it, good for you. If you end up craigs listing your ride, you've still put another bike on the roads in my mind. go for it.
