My vote would be the Winchester Super X3. It comes up and shoulders nicer for me than some of the nicer O/U's I've shot. Great gun for the money, so far I've put over 500 rounds through mine with out a single jam. Seems to be very dependable.

Wingbone hit the nail on the head though, make sure if fits you, even if you buy one that isn't necessarily "your brand", fit is everything! I went to the shop to buy a Browning Gold, but just couldn't put down the Super X3.

Good luck.
