Shop around. Dicks has them for $699 but Academy sells it for $649. As far as I can tell, Bass Pro has no interest in carrying the A300.
I was torn between the A300 and a Stoeger O/U. I went with the Stoeger because I don't go duck hunting - only dove and skeet.
And it's not a stripper A400 or AL-391: they took components from each to make the A300. All the reviews I've read/watched have held it in high praise. One thing I didn't like about it was the hard plastic fore stock. The A400 and old Extrema 2 have hard rubber inlays that make it nice to grip, but the A300 is just straight up cheap plastic. Hardly a reason to spend an extra grand, though.
