I've owned my BSD for a long time. I think I bought it in 1999. This is one tough pin to get decent scores on. I guess I'm not that good of a player.
The best score I've ever got is about 1,500,000,000 with it set to 5 balls. But, I love it and will never sell it. I just changed it back to factory settings (3 balls) and it's even harder!
