RE: O/U shotguns 1000-2000 dollar range
I spent the last 8 months doing homework on Over Unders, and finally decided on the Citori as well. Seemed to be the most popular in the price range that you are looking into. I paid about 1500 for mine, and that was with the dealer giving me a military discount.
Best advice, is to get a list of the polular, known brands in the price range that you are looking for, and if possible go to a trap range and see if you might be able to shoot some of them. Otherwise, buy the one that fits you best, and go through a knowledgable gun shop, not some kid at the local gun super store that just rings up the sales.
The last thing I was told when I was in your shoes, it to buy a B-gun. Browning, Beretta, .....etc
Good luck to you
