I never believed that stepper slots would become collectible - I still don't. but for what you get I'll take a EM any day and should be of more value.I've got to agree with that.
They may be fun to play with backlit reels etc. I my opinion the EMS are a hardy, hardy, well built machine while the newer slots have plastic everywhere and cheap parts. What I don't understand is why the IGT S2000 can be more expensive than the Bally EM's.
