Old thread, but Ill comment anyway. Raindog said stay around $400 so I recommend a S&W 638. I got mine for $359, and I like it better than my KLCR simply because it has SA option, and is still "hammerless"(snag free) My SP101 2" DAO is a nice snub, but its a brick compared to the Airweight 638. I also have a Taurus 905(9mm) and its a good option in the $400 range also. There are lots of good quality, newly manufactured snub nosed revolvers in the $400 range.
Smith & Wesson 638 and Taurus 905
