Don't be afraid to check out J&G Sales, CDNN, and possibly other on-line sellers. They often have security company trade-in S&W revolvers for VERY good deals.
The most common is a 4" barrel Model 64 (the stainless version of the most classic Model 10), K-frame .38 Special -- usually available for under $300. Those guns were carried a lot and shot very little, it seems. They'll still be great when you pass them on to your grand kids. They're usually converted to DAO, which is fine for the sorts of things you'd use a 4" .38 Special for. (Carry, defense, IDPA, and good range practice.)
That's a whole lot cheaper than any new quality revolver. You can indeed try a Taurus or Rossi or Charter for relatively little money, but you can often tell why you paid less than other new guns.
