I have just brought my EM Bally Night Rider up to the gameroom to join his SS little brother. I need to restore the EM but it works perfectly. Have to say I like the play of the EM a bit more than the SS. Nothing says old school pinball better than the sound of the score reels. Would love to add an EM Mata Hari to my collection some day. I would love to see any Bally Twins or other brand EM/SS twins. I know Dayhuff can contribute here. Everyone enjoys seeing his collection. I played all brands of games in the 70s and I have several brands in my collection but Ballys are my sentimental favorites.
