If you really want to help pinball, seek out guys like Levi (Funtorium), Al (Pinholic NYC), Bill D. (pinball gallery), Jay (Pincrossing), Steve K. (Rock Fantasy), Paul D. (Eight on the Break), PAPA / Replay, The guys at Sanctum etc. These guys share their pinballs with their friends and some with the world (anyone that can walk into their arcade) . Getting these pins into a collectors basement so that a handful of people may ever see it , does not have the same effect.
I am also one who might be interested in something , but i would rather see the guys listed above get first shot as they are really hustling to make great events and locations for everyone to enjoy their machines.
Next thread should be "Nominate People who deserve to buy my games" because worthy people are not going to jump through hoops or be "the first one to email." .
I fully understand what you are trying to do , but this is not the place you can achieve that. Get your games into arcades etc. That is best for everyone.
