Haunt your local pawn shop. Look for something that perhaps has been bubba'd a little; crappy recoil pad, driver's license number engraved on the side, etc. If you are beating it up on an ATV or behind the seat of the pick-up....so what? That said, I'd look for an 870 or Mossberg 500 as both work. You might find a 1200/Ranger Winchester that will work too. How many rounds a year are you going to shoot it? 25? 50? They will easily shoot thousands of rounds with just some basic maintenance, maybe a new magazine tube spring every 15 years. Clean the crud out of them, function test, wipe off the exterior every once in and while... and go forth.
