RE: O/U shotguns 1000-2000 dollar range
Browning Citori, just great fit and finish, quality is about the best for the price. The Cynergys are also nice, but there more expensive.
Another option would be a Ruger Red Label, I have never shot one, but I have heard good things about them.
Maybe even a Beretta is you can find one for the price, it would be nicer then both the Ruger and Browning.
