My suggestion is go try out the fit on a few at the gun store. Take your duck coat with you. No point in buying a SBE2 or an Xtrema that doesn't fit.
I don't like Brownings at all; they don't fit me well. Benellis and Remingtons fit me well, so I would buy one of those. You may be the exact opposite. Before spending $800+ its something to seriously consider.
Were I to buy any gun on the market now for ducks, it'd be the 3" Benelli Vinci. They're funny-looking, but nothing out there fits and points as well for me, and they've been proven reliable.
