Quoted from PinMagnet:90's pins are not what you want for your first pin. They are for seasoned veterans who know how to work on them. Buy a new pin or wait for the remake. It seems like a great idea, but it will become very frustrating very quickly.
I respectfully disagree. I got into this hobby a year ago by buying a 1997 NBAFB. I'm not mechanical or electrical savvy in any way. After looking underneath that playfield, I was intimidated as hell. However, fast forward a year later, I can now solve about 90% of the issues that arise in a pinball machine, from rebuilding flippers to soldering wiring. This is because of how helpful Pinside and DIY videos on YouTube are. Since his first pin is Theatre of Magic, more parts and knowledge are out there compared to other machines.
With all of that said, I would recommend a cheaper game. What if you don't like owning or fixing pins? At least you're only initial investment is $2,000 give or take instead of $6,000 on a TOM. Once I knew I enjoyed the hobby, my next purchase was an Attack from Mars.
