I loved pinball as a kid growing up in the 70s. When I was in my mid 20s, I was in a KISS tribute band, and my sister showed me an ad in the Trading Times (yes, that long ago) of a KISS machine for sale for $800 - I bought it. The seller had over a dozen games and told me it was a collectors item, not to play the living crap out of it. Well, my daughter was about 7 and her and her friends (and me) were playing it to death so a couple weeks later I called the seller and told him I needed a decoy - bought a Space Invaders from him for $400.
A year or 2 later a buddy told me about a T2 game for sale in a local sandwich shop. Grabbed it for $800 - it was night and day compared to the other 2 - dmd, ramps, multiball, music, speech, totally different - - that really got me hooked again. I started looking on ebay for games, bought a couple, then word of mouth etc, rec.games.pinball.....Pinside....now we have a couple dozen games in the game room.
