Since you will end up reloading your own ammo for .44Mag it's the most simple thing in the world to load DOWN to whatever recoil level you like. You can load up anything from the softest recoil shy newbie friendly rounds on up to the full pressure SAMMI spec "wrist wreckers" and anything in between. So there's simply no point in worrying over .44Spl. ESPECIALLY since if you find .44Spl it's likely to cost as much or more than .44Mag in factory loads.
The reason I say you'll end up reloading is the cost. Factory .44Mag is up near a buck a round. Yet I can reload full power H110 and 2400 loads for about 28 cents a pop and stout but reduced loads that would be equivalent to .44Spl +P, if there were such a thing, for about 25 cents a round. Considering the savings that's a big difference. Then when you add on the ability to totally control your load power it's a slam dunk decision for just about everyone to reload their own.
As far as the guns go you DO realize that Colt hasn't made any Anacondas in many a year, right? That means you're buying used. But you're also buying "collectable" as well. And that pushes the price of the Colts up into the stratosphere compared to the rest.
S&W make a nice revolver as does Ruger. Ruger also gives you the choice of double or single action models with the Super Blackhawk SA revolver being a price point leader in the .44Mag clan. Taurus SHOULD be somewhat better now that it was in years gone by since Freedom Ventures took over distribution and warranty from the previous losers. But a somewhat higher percentage of Taurus guns seem to come with warranty issues. But I understand that if you get a good one or once any bugs are worked out that they are not a bad option.
