It's too dark now for a photo, but I trash picked a 70's vintage Raleigh LTD, the chrome is kinda crusty but it's a 23". The world is full of old 3spds. you just need to look in the right places. Big Auction site = big$ Thrift Stores, Yard Sales or make a friend at your LBS and the prices will be more in line. Still, the best deals are on trash day.
