I would look for a good used Ruger GP100. I picked up a slightly shop-worn, blued model for about $400 a year or so ago and have NOT regretted a bit. Check the "gun and pawn" places.
I do think i saw one of the old "porkchop" style dan wesson .357 revolvers for sale on thefiringline the other day.
Dead Bears, the only good kind.
