My vote is for a 20 superposed you might pick one up for only a bit more that 2 grand... say 2,500.
I would go for the 28" barrels. ( I have 2, one a two barrel set with 26"/28"the other 28"s). Points like a wand and if you want an o/u can't think of a better gun for that price range. The newer 28 o/u weigh more and don't have the feel. I have a Citori Grand Lightning w/26" and it is whippy and heavier than the 20 ga super.
An alternate would be a sporting version of the 525 with 30" barrels, not real light, but swings well. Will shoot forever. I don't think the ruger can stand up like a browning.
