Mill, I just came back from my local gunmonger and this is what they had...
A SS New Model Blackhawk in 44Special was $599, the blued one was right around $500. They didn't have any other calibers in a Blackhawk, but IIRC, the others aren't much cheaper. That said, around here, you can find 357mag Blackhawks for roughly $350-$400 in good shape. If you don't mind used, it might be worth your while to hit Gunbroker. It's not as if you could wear out a SS Blackhawk in 357mag and if you did, it wouldn't be hard to refresh it.
