I found Pinside back in 2008 when I was expanding my collection, and loved the rankings and comments sections for the machines. The forums weren't very active back then, so I would go lurk at RGP. I also would go to RGP for tech help, and still do search the archives there for repair info. I didn't have any clue how active this forum had gotten until recently. There is no comparison for me between the two, now. RGP is where I go for large, global searches for obscure tech help or to expand a search for something I am trying to find. Pin side is where I go to chat with other pinheads.
