For years I was the only one on the local skeet field with a double. In the past year or so some of them have either dug a double out of the back of the safe or gone out and bought one. However most of those are fairly inexpensive guns: a CZ hammergun, a BSS, etc. None of them are buying the higher end guns. When I go to other shoots (sporting clays and 5 stand) my SxS draw compliments and interest, but I rarely see another double unless it's a Parker, LC Smith, any of the older better quality American makers and an occasional Win 21.
I almost never see a British, French or Belgian SxS. While other shooters appreciate these guns, they aren't going to spend a lot of money to buy one.
