Take your wife to the gun show this weekend and check out the different revolvers and have her fondle, feel the weight and see if she can pull the DA trigger. Don't buy at the gun show (most dealers there are way over priced), unless it is from Randy with R&S, he usually has a good selection of revolvers and his prices are good.
EAA has a snubbie revolver in .357, the Windicator I think is what it is called, and Charter arms has one too. Both of there will be in your preferred price range.
