Welcome Anthony. Best bet (especially for your 1st pin) would be to buy one from a collector/hobbyist and good luck with the hunt .
Good advice!!
Dealers are good to go and look and play lots of different machines, but leave your wallet and good car at home.
Have a look at the way dealers clean and repair machines then look at another collectors game.
One does very little to maximize profit and the other will do everything for love of the game.
