I just picked up a Browning Citori Grand Prix Sporting. They along with the 525 sportings are discontiued models and are now the 625's. Nice guns and I love mine and if you can find them they are heavily discounted into the $1700 or so range. I bought mine in PA at Tanners in Jamison, PA but it was the last GP they had. Check the Browning website for dealers in your area and check them out.
I've got the Browning Sporting Clay's edition, with 30" barrels, and I had a Briley UltrLight sub-gage tube set made for it. I've shot competition trap and skeet with it, and recreational sporting clays. It's the perfect gun!!
