so... I have many of these revolvers, love them & still have more coming & being built...
personally IMO, you should also buy the Ruger, it's a solid investment, agree with the suggestion to get adjustable sights, since it sounds like you want to play with different loads...
I also have several Tarui, & several Uberti's so you know I'm talking straight...
the Taurus is a practical gun ( when you get a good one, I have several, & never had to send one back yet ) but they are not as smooth, & leave you feeling like they need "something" the resale of a used Taurus is dismal unless you are talking a few rare & desirable models...
the Uberti's just have "the look" & a "feel" you certainly don't get with a Taurus, but their steels & hardening are less "durable" than either the S&W's or Rugers ( yes they send out some beautifully case hardened guns ) many are more true to the Colts they were designed around, but they should only be used with standard ( very anemic ) factory 45 Colt loads ...
I'm more disenchanted with new S&W's as far as quality ( yes I've had some issues, including sending one revolver back 3 times for the same problem ) but once you get a good one, they have a feel that is mush more refined, & resale on the S&W is likely the best, model for model than any of the rest, excluding Colt
Rugers are general know as the strongest, IMO, one of the best values right now, you get a lot of revolver for the money
if I were you, I'd probably buy a used gun, either S&W or Ruger, or buy a new Blackhawk with adjustable sights, a blued one, if the stainless goes beyond your budget,,,
this is just a fraction of my revolvers ( these all single actions ) & I'm building a Uberti Colt Walker cartridge conversion to 45 Black Powder Magnum right now, so I'm pretty familiar with what they are putting out right now... that said I'm buying a Uberti Stallion, as the base gun for my next custom ( so my latest 2 customs will have been built on Uberti guns, but both are low pressure customs, nothing that pushed the high end of 45 Colt
