There's a guy on ebay named Jurgen, userid cert06, who specializes in selling CLA'd folders. He's got a pretty good reputation among apug buyers. After watching quite a number of auctions, his buy-it-now prices are really close to the eventual bid price. Depending on model, features and "cool" factor, he has auctions right now ranging from $125 to $350. All are in top shape. I had GAS really bad recently and almost bought one, but decided a new lawn mower would improve my life more than another old camera would.
I have bought two folders from Jurgen, very happy with both. His prices are only a little over the norm, but for that you get a properly serviced camera from a proper company.
