USFA makes two models in 22LR, one is a six shot called the Plinker and comes with a 22MAG cylinder also. They also make a twelve shot 22LR only. Good luck in finding either right now.
Found it: European American Armory "Bounty Hunter." Some sources say it's made in Italy, others say Germany. Alloy frame but built to the full size of the 1873 SAA.
The New Vaquero in .357 is probably my favorite gun to shoot. The sights can get a bit fuzzy at times but I don't do much long range shooting with it. Although its a bit on the big and heavy side, it's makes a nice trail gun as well.

I also recommend the Ruger Blackhawk or the Ruger New Vaquero. I have the original Vaquero (bright stainless steel) in 44 Mag with a 5 1/2" barrel which seems to point perfectly for me. Since you want the 357 Mag version the New Vaquero should fit the bill nicely.
+1 0n the Beretta Stampede. I just bought one 6 months ago and the finish (ss) and trigger are nicer than any of my 6 ruger sas. I got close to 1000 rounds through it with no problems.
