I hate cleaning my Beretta 391, and I wouldn't trade it for any other. No matter which one you buy, after you take it apart a couple times, you'll wonder why you worried about it.
I would shy away from the ole Browning auto-5, that's a whole different animal. Don't get me wrong, they are wonderful shotguns, just different.
