I've had my mossberg since i was 12 and it's never once failed me or even given me a fuss after all the crap I've done to it. Plus they are cheap. But it depends on what you want it for. I only turkey hunt and do a little bit of bird hunting.
This is what I would get:

Also look in the 2007 Remington catalog they have a fantastic new tactical 870 that can be had in camo with the Knoxx adjustable stock.
