My brother has a Stoger and yes you can find them at very good prices when on sale at Dick's. My brother paid $299 but since I have seen them sell for $249. I was leary about the quality but his has held up well. It is a very good looking shotgun, I just can't shoot it as well as my 870, Ithaca or Moss 500. I also had a Winchester 1300 that I sold just because it wasn't a Rem 870 or Mossberg, I feel stupid now because it was a good gun. I think the Winchester was every bit as good as the Mossberg, it just doesn't get the press because they are not as popular. Pretty much any good quality pump is going to be pretty darn good.
When shooting sheet, I couldn't see any advantage of the SxS over the pump. I am just as fast with the pump and it seems to point better for me. Maybe if I had learned on the double bbl, I would be better with that.
