I know Benellis are the bomb and all, but I have always had a thing for some of the old Ithaca shotguns.
My all around 12 g shotgun, the one I have used for skeet shooting with friends and for bird hunting is an old early 70s model Ithaca XL900 semi auto made by SKB of Japan for Ithaca. I only see one on Gunbroker as of now. Not really anything expensive, and it's a gun my dad bought for me back when I was about 13.
It's smooth as hell and it never fails me. Handles everything I throw in it. The one on Gunbroker is at $399 for a starting bid, looks like new.
Just throwing that out there, I'm sure you are looking at something a bit more substantial and new.
I have shot next to guys with really expensive shotguns, they usually end up shooting my Ithaca and loving it. I've got a 1949 Model 37 Ithaca pump 16 gauge...I love it because it does a couple of things...it ejects from the bottom and I can hold the trigger and slam fire it, emptying the gun on a single trigger pull while working the action. Again, another gun that I inherited from my dad.
