I'm another one who thinks that the idea of a revolver and a handy carbine chambered for the same cartridge is just as practical now as it was back in 1877 when Colt started chambering their SAA for the .44 WCF.
I have three different .357 Mag carbines, and love 'em all. The Marlins are about the easiest to find most places, and they're fine weapons - rugged, accurate and well-made.
I'm extremely fond of my Rossi "Trapper" model 92, too. It's 16" bbl, 5 1/2 lb. weight and 35" OAL make it a joy to handle and a breeze to pack. Also very accurate, reliable with any .38 Spl. or .357 ammo except WCs, and a hands-down favorite with my younger nephews.
My personal favorite, and the one I'd hang onto if I had to pick just one, is my IMI "Timberwolf" pump. No longer made, unfortunately, but the best of the breed in terms of its outstanding accuracy, slick operation and ability to adjust the butt stock to optimize the fit to the individual, making it absurdly easy to place your shots precisely fast.
I don't think you could go wrong with any of them.
