Around 1990 or so, I happened to come across a 1954 Williams Super Pennant pitch & bat baseball game. Saw it in the arcade at the old Fantasy Farm amusement park in Middletown, OH. The operator said that there was 'something wrong' with it and said that he would sell it if I was interested. Long story short, I bought it for $250. A friend at work was able to fix the minor problem with the game. It's operated pretty much flawlessly ever since.
A year or so later, I got the itch to buy a more modern arcade game. I searched and searched for the 'right' game and wound up buying an Earthshaker from Associated Vending in Cincinnati (a great vendor, btw). Still have it. Great game.
Fast forward 20 years to March, 2011. The display on the Earthshaker was 'out' and I finally had it repaired. In so doing, it piqued my interest in adding another pin. Did some on-line research to find out what I had missed over the last 20 years, haha, and decided to find an Addams Family. After ALMOST buying one from a 'mysterious' seller, I bought one from a reputable private owner here in Cincinnati. Good choice!
The same day (!) I also bought a 1991 Slugfest from another reputable private seller in another part of Cincy.
About 2 weeks later, I bought a World Cup Soccer 94 from another good guy, this time in Columbus, OH.
Then, about a month or so later, I found an LOTR in Loveland, OH on ebay. Bought that, too!
And now, the quest continues . . . . . .
