I own one, but I dont shoot it. Right now its a collectors peice since Semi Auto Shotguns may be going the way of the dodo in the election. Its a well crafted Shotgun, they fire beautifully, and they are a pleasure to hold. But, you can get a great shotgun by way of an 870P too.
The only benelli semiauto I've personally owned was a 12 ga legacy but have shot others. I sold that gun and am still kicking myself for doing so(needed the money in a hurry). I'm going to buying another benelli soon as I couldn't believe how well it shot and how little recoil was transmitted to shoulder. In short-YES they're worth every penny if you can afford 1.
