The older HK SBE's are highly sought after here in Arkansas, especially if it has a 24" barrel. I probably don't have to tell you, but with the older HK guns's some guy's still take the chance and do the Benelli shuffle. I have never found the need for shooting 3 1/2" shells to kill ducks. But to each his own. If the HK Benelli is in excellent to new condition, it will appreciate in value. If you are young, and don't mind the weight of a gas gun, the Beretta AL 390 would be hard to beat.
