Well, I didn't buy one of the Knight Disks I've just been looking at them as I've seen those two both pretty cheap. Both of them say they take the orange disks.

My buddy with the Knight BK92 still has it and he told me if I decided later I wanted it I could have it. He said I was the only one that's even asked anything about it so far. It's a good friend that has it so it's not a for sale add. He has tried to sell it to others but I think the price he told them was quite a bit more. In fact I know it is as I've been there when he has been telling a few people about it. If I decide later I want it I can still pick it up if someone else hasn't.

I'm just not sure I want it though. While $55 isn't very much like you said. It's still almost halfway there on one of the other muzzle loaders which are much more what I'd want. I really don't even need another one anyway.
