Cruise your local bass pro/cabelas used gun rack, find a used 11-87 Supermag/Special Purpose. Avoid anything that has "sportsman" on it like the plague. You want the 80's to EARLY 2000's vintage, the ones that feel like a tank in your hands. All the boat-paddle abilities of the 870 with the convenience of auto-loading. For $500 they're going to keep running way after the new hotness guns are gummed up and done for the day. And when you fall on it, throw your decoys on it, slip and spear it in the mud, close it in the tailgate, have the dog piss on it, etc, you won't cry because it's a $500 shotgun with 2 moving parts.
