I hear people bad mouth Pinside from time to time. These are people who don't use the site properly. It's a great tool for repair tips and buying/selling games. Most people that complain about it to me are the ones who get an ad forwarded to them (like some crazy priced $65,000 Twilight Zone.) The response is always "people are crazy on the website." The other thing mentioned lot is how is just a place for people to whine about how bad the new games are (playing and quality.)
I do my best to support the website. I bought a game yesterday from a first time seller. He asked if I always pay the fees. Always, if its a sale because of Pinside. I told him it is only $35.00 and it goes to something that makes the pinball world better. He paid the fee this morning.
