Lots of choices out there. I've heard nothing but good on the stoeger 2000. Made by benelli for stoeger. Avoid the Charles Daley auto loaders. They have a lifetime warrently but you'll need it(and often). Their pumps and doubles are good guns though.

As far as pumps go you'll have lots of choices in that price range. I suggest trying them out and see which one fits you best. Really it's spitting hairs as too which one is better. Can't go wrong with remington, winchester, browning, benelli...
