Quoted from bintzknocker:
I have the same issue. So I went to home depot (my local hardware store sucks but thats a different story) and bought a switched outlet. (the one that has a switch for one of the outlets). Put it in an electrical box. Cut the female end off an extension cord. Wired the female end to the switch so that the outlet is hot when the switch is flipped. Plug Chexx into the outlet, plug the male end of the extension cord.
Lock the coin door and there you go. You turn the game on and off with the switch instead of having to go into the game.
If your wall are already finished, wouldn't it be difficult to wire in the "switched outlet". Would be a great solution if it was already done. I guess, if you're in an area where there is no moisture you might be able to run the wiring behind the baseboard. I guess you could also fish the wire directly above the outlet. Still...not up to code and not really an easy fix.
Also to the best of my knowledge any cheep outlet can be turned into a switched outlet. They have a breakable connection between the two outlets. At that point you just need to wire them correctly.
PS: Just to be a troll, with the debate over the MMR. Wouldn't you pay a premium for an original Chexx?
