russian baikal mp-153, now imported/sold by remington as the spartan spr-453: about $300, and a better built and more versatile gun than both you mentioned. gas-operated with adjustable bleed-off, will shoot 1 oz. 2 3/4's all the way up to 3.5" mags. very light recoil, weighs 8 lbs. and is somewhat muzzle-heavy(which i like in a waterfowl gun). the sx2 is a great gun too, just $300 more for the same performance. the stoeger uses a cheap benelli-knockoff inertia system and only shoots up to 3" mags. the mossy shoots 3.5" but won't cycle light 2 3/4" loads, and their factory will tell you that. as far as camo goes, buy the black synthetic and have fun with some krylon camo paint, looky here:
