If you can find a lightly used Winchester Super-X 2 or 3, you won't be disappointed, they'll cycle anything (the 3 1/2" guns have a little trouble with the REALLY light trap loads, but nothing else), and they use Browning chokes (I have a strong suspicion that the gun pictured up there is nothing more than a Super-X with a Browning label, and a jacked up price tag). After the gas guns like this have been around for a while, I doubt anyone will make an inertia driven auto twelve any more.
I will second your opinion that the Winchester Super X2 and X3 shotguns are also very good guns. I used to shoot a Super X2 myself. But I ended up giving that shotgun to my son. And I then bought a Beretta 391 Extrema 2 to replace it.
Here is my son with his Super X2:
As far as a price gap between Browning and Winchester, it is actually very marginal on new guns. Both of them, and also the Beretta 391 Extrema 2, are all basically in the same price range.
Regarding the new Browning Maxus shotgun, though, you are clearly misinformed. This was one of the major new shotguns announced at the 2009 Shot Show earlier this year. And it only finally started shipping last month.
I mainly mentioned it because it is so very new, that few folks yet know about it now being on the market. Dealers have only had it now for a few weeks. Feature-wise, the Browning Maxus is enhanced to compete well with the Berettas.
My only concern with the Maxus is how very light it is. 6 lbs 15 oz seems awfully light for a 3.5 inch 12 Gauge Super Magnum. In contrast, the 3.5 inch 12 Gauge Magnum Beretta 391 Extrema 2 is 7 3/4 lbs, and the 3 inch Magnum Beretta 391 Urika II is 7.2 lbs.
The Maxus sure has some great features, though. Here is a web page with more info about it:
