A good used semi, for upland means you don't need a magnum gun, nor even screw-in chokes. Imp Cyl would likely do all that you need. I'd look for a Rem. 1100 (or 11-87 if it pops up) or a Winchester 1400, with a 26" or 28" IC barrel if you can find it, but other fixed chokes can be opened up cheaply.
A Browning A5, as nice as they are, is a heavy gun. Too heavy for upland work, IMO. And the more versatile and modern the gun, the pricier it will be (i.e. 3" chambers, choke tubes). Very few hunters want to be 'limited' by a 2-3/4" chamber and a fixed choke in a gun that can't handle steel, so these guns sell for less.
