Good .357magnum revolvers include the Ruger SP101 & the mid frame GP100 series.
The rare limited ed Talo/Wiley Clapp version is a great value. You may find a few online; www.gunsamerica.com www.gunsinternational.com
I saw a used Ruger Talo .357magnum at a gun shop in Norwalk CT. It wasn't cheap but will hold its value.
A S&W M&P R8(used by the elite ESU of the NYPD) is a good idea but they are costly & the huge N frame size.
