The Browning Buckmark Camper. Nice, easy trigger. Adjustable rear sight. Not very expensive either. Of course if you wanted to go the single action route, there's the Heritage Rough Rider. Cheaper than a Ruger Single Six. I found a Ruger at Bass Pro the other day: 4 5/8'' barrel, plain grips for $399!! The Rough Rider goes for about half that. Maybe not as durable, but it should still last for a few thousand rounds.
