I've owned or own all those you mention. Another choice is the reproduction of the Smith and Wesson #3 single action 2nd model Russian. The one I have is 45 Colt, but I think it's available in your caliber as well. The 44-40 used to be my favorite western cartridge and is still dear to my heart. There are also Smith and Wesson New Model #3's floating around from when they re-issued that model maybe twenty years back. They are not inexpensive. The Italians have also made that model with Beretta's Stampede probably still available NIB at gunshows.
If you're into the closing days of the frontier, the Bisley, also available from the Italians, is a great choice. I have a Beretta and it is a fine weapon.
Slightly off-topic but...I remember when the Texas Sesquicentennial Commemorative Smith and Wesson came out in 44-40. A few years back, I saw one in a gun store. Alas, I didn't snap it up. I should have.
