Quoted from jcar302:

When I finally tried the original board (11) a few months later, it didn't work right, I sent it back in and he claimed he never worked on the board. Said he'd never fix a board with as much battery damage. Sound didn't work, which is why I sent it in. Then refused to return it to me, said i'd get $100 credit towards an aftermarket board, which was $400. Never took him up on the pathetic offer. That would have put me $500 out of pocket, and the rottendog boards don't work on High Speed.
So $200 and a board down the drain.
I only had one pinball machine at the time and it was my first.
I still have every email and the paypal receipt.

Overall, NOT good experience.
