Hey man! The Pana line of control box superguns are rock solid. They were made by KIC's, aka Kyowa International, the company that made the very first supergun in Japan back in 1986. They're of excellent quality, with some unique buttons that are different from Sanwa and Seimitsu. It uses the same switch as a Seimitsu button, but the button housing and plunger are different, effecting the feel. They're some of the best buttons I've ever used. Pana boxes also have the best RGB and sync output of any of the Japanese superguns I've seen. The original Pana Twin and Pana Custom are a little small for 2-player use, as there's not much space between each players controls. Also, the Pana Twin has almost no palm space, so if that's something to keep in mind. If you want more space between player controls, go for a Pana Custom Long or Pana Twin Long. They released those in mid 1995 to address the space issues of the original models. If a mahjong panel is a must, then the Twin is for you, but if you can live without that, get a Custom.Yo Dig! Nice PCB collection! Ive always been curious about the Pana guns, what are they like? I couldnt tell if they were like very sought after/high end or what, but when I was investigating superguns initially, they would always come up.
Also, just so you know your MDIII gets CONSTANT adoration and play, and I show/hook new people on the game all the time.
