I have Faces, Cherry Bell, Super Straight, Mars Trek, Gamatron, and Pole Position.
I am sure I will find a prospector soon. They come up so often, I just am in no rush if the price is wrong. Also have had the opportunity to buy butterfly a few times. Unfortunately the cabinet is always roached on them.
Just out of curiosity, why is this limited to sonic only? Segasa is the same exact company.
I am just tossing this out there. I would absolutely love to get my hands on a Casino Royale, Jai Alai, or Joker's Wild, Odin Deluxe, Hang On, or a Birdman. If anyone has any of these and was interested in selling, please let me know.
