Prices for SRHs seem to stay high. The big S&W Magnums don't hold their value as well.
But you want what you want and anything else won't scratch the itch.
The 480 always seemed like a round for guys that wanted a handgun that sounded huge but really doesn't have the punch that the name implies. I have never shot one though, just looked at the ballistics.
SRHs are nice revolvers though. I hope you track down what you're looking for.
