I will add to the dogpile and say that the only real option in a <$800 single action revolver is a Ruger of some variety. For a DA gun the Ruger Redhawk is pretty darned tank like as well, although an N frame S&W in 357 would consume a fortune in full power magnum ammo and still keep on ticking.
If you can afford enough ammo to wear out any of these guns then the choice is essentially irrelevant: replacement or repair costs would be a minuscule fraction of the total shooting bill. If you're actually wanting to know which one you can overload the most and not blow it up then I don't really know if the cast Ruger frame can take more abuse than the forged S&W, but the offset cylinder notches on the Redhawk are a plus.
I guess the ultimate in overloadable <$1000 guns is a Redhawk in 357 because of the offset notches and beefy cylinder walls.
