RE: Over/Under thoughts.
You should also consider the Franchi Alcione the field model is around 900 and they are discontinuing the Alcione line so you might be able to get a great deal. I like that with the Franchi you have the option of going from 12 to 20 ga without doing any gunsmithing, and if you are into shooting clays you can also get a set of 30" ported sporting barrels. I have the Alcione with all the barrels, and for the money you cant beat them.
