If you want to heavily load the .45colt, you could also get a Dan Wasson or a Colt Anaconda, used, if you could find one. Ruger used to make blued Redhawks with 5 1/2 or 7 1/2 barrels in .45colt. They are a lot harder to find than the .44mag versions.
If you don't want to load any heavier than moderate loads, the S&W Mountain gun is a sweet revolver, but is in stainless.
If I find one at a time that I am flush with cash, I want one just like bountyhunter's. That gun with some fancy wood stocks would be my idea of perfect. It is good looking with just the right balance of portability and long enough sight radius. Plus, it can take loads hotter than just about any other gun except custom five shot Ruger sa's.
