aren't the new ones "inertia driven" like a benelli? the way i see it, if i'm gonna put up with the maintenance required with an auto, might as well have the added benefit of recoil reduction that you get from a gas auto. otherwise i'd just stick to a pump.
with a price tag of $1500+ it's way out of my league for a duck blaster, so i guess it's kind of a moot point for me.
