A 357 offers a little more diversity being you can use it to shoot 38 spl. as well as the 357 loads. I had a Taurus Mod.66 wheel gun while back but didn't keep it long. It worked pretty good I guess.I wanted another pistol and it fell victim to the chopping block.
Have you looked at any of the Ruger revolvers? They also are not too expensive and they make a great revolver. The Blackhawk AND THE GP-100 are both really nice weapons. I think the Ruger gives the shooter a little better grip over the Taurus but thast's just me.
