Check gunbroker, there's always old PPC guns for sale there at reasonable prices. Even though most have had a ton of rounds through them it was usually light target loads so there wasn't a lot of stress on the frame and they've held up pretty well. They're usually DAO with light, slick actions and very accurate shooters. I see no reason one couldn't be used for general range and plinking fun and home defense, though most are impractical for any sort of carry.
