Personally I'm a fan of EM machines and wish I could own a couple. The artwork, sounds, simplicity of the playfield are all appealing and can be a lot more fun to own than some of the current DMD era pins as for some reason they seem to not get as boring fast.
In Australia though I'm yet to find an EM pin in good enough condition to warrant the price, seems to be rare here and in most cases priced higher than the entry level DMDS even when in poor condition. When I see one I'll snap it up though, if I was in the U.S i'd be buying loads for the prices you see Em's going for.
