Here's how it goes. Buy first game. Then you're immediatelt struck with the disease and you start scanning cl and ebay all the time buying up games right and left because they are such a good deal. And as you start to fix them you realize that good deal wasn't that good at all. Now you have several projects that you eventually find out you don't like the game at all. Then you try flipping it on ebay or cl. And you have a terrible time trying to get rid of them. Then you decide to restore a few games that are keepers. And then the last part of your journey ends with you deciding you've got all the vids you want.
Enter the number od the beast. You'll get hooked on pinball which will suck your bank account dry. You'll sell off a couple mediocre. Vids to help fund the next pin. Also a common thing us men do to appease the wife. After you buy 3 to 5 pins you finally figure out exactly your likes and dislikes in pinball and sell off or trade to get a better suited pin. Eventually' like God himself did' you will look around you and say' "it is good" and you will rest (actually for once know what you have is exactly what you've wanted).
I'd add more but typing on a droid sucks! Welcome to the madness
As others have said, "welcome to the madness." I can attest—it never stops at one, and I even started with a multi-machine! Eight arcade games and one pinball later, I had to rearrange the room to fit it all. *sigh* But "ain't it purty" when they're all lit up at once in the dark?
