I think I found the 908 you are referring to. It does look to be in really nice shape.Maybe this mention can help somebody out There.
* A good bit of reading suggests that most people in this S&W ' interest category ' highly prefer the 3913 or 3914, due to the all-metal components.
I suppose most folks do prefer the premium line guns all other things being equal. The problem is that they are almost never equal when you are talking about used guns of different ages and with different histories.
The premium line guns are great, but I'd take a later vintage as-new value line gun over an older "used and abused" premium line gun every time. However, I may be in the minority with my opinion.
