These are the only 3 machines in my collection and the only ones I really considered owning. I absolutely love the artwork and even though Superman is DC, the style of all three are very similar. Spiderman and Superman were both non-working and Hulk is in very good condition but have been giving me trouble lately.

As others have said, parts are fairly easy to find for Spiderman and Hulk, but harder for Superman. Superman/Atari parts just take greater patience and luck. I feel like right now there are tons of parts out there available for all 3 machines. (Hulk and Spiderman playfields for sale on Pinside, Superman backbox and boards on eBay).

Best of luck in your search!
