A friend of mine told me that the cheapest way to buy a Benelli was to just go in a store and buy a Benelli. He said a more expensive way was to buy a Mossberg 930, realize it wouldn't work, and take a bath on it when you traded it in on a Benelli.
I'm not 100% sure you have to buy a Benelli to have a reliable semi-auto shotgun, but every indicator I've seen has said to stay away from the Mossberg 930.
