If I was getting one pin I would buy the 5k loaded ghostbusters I see on craigslist, 2 pins and I would get a classic Bally Williams dmd from the 90's and another 90's or newer dmd. There is a long list of ones I would consider from the 90's but my favorites would include getaway, shadow, indy 500, no fear, nascar, fish tales, too many to list.
