What's the fear? It's just another forum with a lot more people. I usually just scan through it daily and see if there's any posts that interest me or pertain to any of my machines. If so, I can learn a lot. Lots of good people there who have helped me troubleshoot and fix some issues. You'll learn quickly who is a guru and who is full of shit.
Stay away from Mike Gallagher (in Dayton/ Beaver Creek Ohio), Creek pinball, aka Tiger, aka, Beaver pin ball, aka Mike G ...aka... a dozen others. I've dealt with him before and wouldn't trust him for shit. Do a search on him and you can read flame wars for days on him. That's the only person I personally would steer you away from. Actually, the first and ONLY person in this hobby I've ever posted such a warning, if that tells you anything. He posts daily of looking for or selling a ton of games, makes it SOUND like he's a giant op with a huge warehouse, but just screws people from his home. Makes up various aliases (including imaginary brother when dealing with me) on Ebay and RGP...I guess you'll find people like that anywhere if you look hard enough. You'll see him sooner or later on RGP, just beware.
RGP...lots of great reading, a daily stop...I'm off to there now!
