Someone already beat me to it, but the Rossi is the only one (other than the Armscor and Taurus .38s) I know of that is a small frame 6 shot near DS clone ("D" frame or what I also call J-Plus) on the market, and is .357. (I'd shoot .38s and +P's in it mostly anyway in a (any) .357 snub).
A-B'ing the two at a LGS, the Rossi is amazingly spot-on in all dimensions other than being beefier in the frame just ahead of the cylinder--than the DS. Old school hammer-mounted firing pin and, last I saw, no lock, plus Taurus lifetime warranty IIRC. Actually a nice piece, especailly for the price. Some have reported early problems, most not. I'd check out out anyway. I won't disagree with the existing and future posts extolling a used K-Smith or Ruger Speed Six for most duty, but those are larger/heavier. But, if your criteria is "same as Detective Special,"--ie, small frame, six shot--and new, the Rossi/Armscor/Taurus route is the only way to go. If .357-capable is added into the mix, the Rossi is the only one I know of.
