I just picked up a Winchester SXP defender last month for $350. It's the nicest pump shotgun I've ever held. Smooth, light and tight with a chrome lined open choke barrel. Took it out shooting last weekend and its probably one of the most advance pump shotgun in the world. Rotating bolt, aluminum receiver, pump assist and easy 3 main assembly breakdown. Accommodates 2 3/4 and 3 inch shells. I believe it will work with some 1300 parts but haven't confirmed this. There is also a waterfowl barrel available for it. Minimal recoil and I've heard a lot of service members praise them. Looks mean as heck too. The Turks make some great shotguns so don't believe the detractors. .300 Weatherby Mag, what did you dislike after handling one? Winchester knows how to make shotguns and this is to my knowledge their most advance pump to date. It's all business and I absolutely love it.
Just saw this offer over at Bass Pro Shops. It might be a viable option as well.
