Joining the club!
I operate a Banzai Run on location at Premier Lanes in Chesterfield, Michigan. They have about 30 pinball machines with a lot of System 11s, so BR fits in there well.
The biggest issue I had was the darn subway in the back playfield was cracked at the bottom. I tried to do fixes here and there to avoid replacing it and spending $100, but the ball kept hanging up. I ended up buying a new subway and have not had a problem with it since. It was well worth the money.
