Callahan, Until a couple of weeks ago, I was on the same mission you are on now. I had narrowed my search on two solutions: Ruger Redhawk or Colt Anaconda. My personal opinion on the Redhawk is nice sidearm, but butt-ugly, and I have a Colt King Cobra I love so I was leaning towards finding an Anaconda. My caliber of choice is .45LC, and miracle of miracles, I found exactly what I was looking for at a gunshow: Used Stainless Colt Anaconda, 6" barrel in .45LC in terrific shape for $550.
But, if I were in your shoes with the limitations of new only, and .44Mag because you have the brass and reloading dies, I'd definitely snag a Redhawk.
