gunbugbit,
I am a revolver guy. I have lots of everything that spins.
That being said, the Ruger SP101 is perhaps my least favorite. I have a bad prejudice, I hate poor factory triggers.
If you like that wheelgun, you gotta try some used vintage hawglegs.
Ruger security sixes, SBH 357 Maximum,
S&W 13, 14, 15, 19, 25, 27, 28, 29, 586, ...
Colt 3 5 7, trooper, diamondback, python, cobra, SAA, New Frontier
The 357 Maximum and the Diamondback 38 special are my two favorites.
You will love any of those listed. Find good examples and enjoy the hunt.
You get what you pay for.

You seem like a discerning kind of shooter, instead of the vanilla Redhawk, you should look for a United Sporting Arms Abilene, Seville, or EL Dorado. These are some of the very best SAA's you'll ever see. Prices can still be reasonable because no one knows about them except maybe older silhouette shooters. These are magnum shooters used by custom builders on big-bores.
