I didn't realize how coveted the EM version was...I know they didn't make too many, but they seemed to have made a helluva a lot of the SS version.
I have the SS version, and I love it to pieces. Seems like the best compromise to me would be to save thousands and buy the SS, because after all, the playfield is the same and they both play the same.
Then again, if you're a mad collector that has to have the rare bird in the cage, well...you don't need me trying to sell you birdseed.
