As far as double action revolvers go, Colt only seems to be making the Cobra, in .38 Special. They have sold the "cowboy" style single actions all along, but they're mostly made in Italy, by Uberti, I think. Maybe they still do some finish work on them in Hartford, I don't know...
The Trooper Mark III and the Diamondback were both nice pieces but they've been out of production since the 70s or 80s. The Colts were always rather expensive for what they were and it seems that Ruger and Smith & Wesson pretty much cornered what remained of the wheelgun market. Both tend to be less finicky and more robust than the Colts.
