No one has mentioned what I feel is the best quality for the money o/u out there...BERETTA. To keep under $700 you will ofcourse have to go used, which is the route I took. I picked a used Beretta Onyx in really nice shape for $599.00. I have since sold it and upgraded to a Beretta Silver Pigeon. If you go new, consider spending $250 more and look at the Beretta Whitewing. It had a great review in last months issue of the NRA-American Hunter Magazine. Browning, Ruger are also nice. I just heard from my gunsmith that Benelli is running the show for Stoeger and have improved the Stoeger quality level greatly. May be an opportunity there as well. GOOD LUCK, YOU WILL LOVE THE O/U.
