Used to be the Charlies Angels EM version that I chased down for 12 years until I finally got my hands on the only one I've ever seen in person, serial #1001S. I've also been looking for my other last Holy Grail which is Bally's Bigfoot. Not sure on that one but I'm guessing at least seventeen years now. I have an original backglass, just need the game to put it into.......LOL.
