I'm really looking at collecting gottlieb hulk, spiderman, and Atari Superman. I'm familiar with system 80, so I know what spiderman will be, but not familiar with the other two systems. I would like to hear opinions on the game play, and reliability of these specific machines. Unfortunately, Superman is my most wanted of the three, but I've read negative thoughts on reliability and getting parts. I know these are all slower games, but theyre all beautiful and I'm more interested in the retro collection feel. Any thoughts appreciated. Thanks
