I'd recommend a S&W and Ruger as a close second.
Will you notice the difference between a Ruger and a Smith? You'll notice a slightly better trigger on the S&W, and they feel a bit better balanced in hand (subjective of course), But other than that? probably not. If you want to shoot really hot loads (like Buffalo Bore) then you'd probably prefer the Ruger. If you don't have to shoot the hottest loads around, you won't notice a durability difference between the Gp-100 and the 686.
Will you notice a difference between the Ruger or S&W and the Taurus, IMHO, yes. Everyone, that's EVERYONE I know who's bought a Taurus has had to have it serviced.
Also, i don't know how prices are up there in Hell (purchase permits for crying out loud!), but here new Rugers are about the same price as new Tauri. used Tauri are considerably cheaper than used Rugers, and there's a reason.
As I've said in other posts, I've never shot a Colt revolver, so i can't give a positive or negative feedback on them.
