I picked up an Italian made Beretta 390 20 ga, sythetic stock with the one inch spacer (to make a shorter LOP for my kids), off of gunbroker a while back for around your price point. Oh, it still had the orange Itialian gov't tags on the barrel as it had never been shot. I fixed that problem very quickly.
Love that gun. Shoots like a dream and is easy to clean. I also have a 12 ga 390, a DU with nice wood. Love those softer shooting autoloaders.
They are are also very adjustable to get a good fit with shims from Cole's.
I've had it about a year, and am still pleased with it. Now I just need to get my wife fitted for it and take her out to shoot some skeet.
