S&W 686 in 4.2 or 6 or S&W 629 with 5 inch barrel. You can shoot special if you want to shoot lots and don't want to deal with too much recoil, or you can ramp it up and have some fun with the magnum loads. The 38/357 is quite a bit cheaper ($0.40 - $0.50 for 357/38 vs $0.80-$1.00 for 44) but 44 is cooler. I have the 629 4.2 and I love it. I think it is one of the most versatile, modern classics (and my homage to Elmer Keith).
