I am also in West Michigan. I don't have any empty cabinets for you, but it is nice to know there are others in W MI into this obsession.
I just picked up three cabinets last week for $50 each. Allegedly they all were dead, however when I plugged them in two were working great. The third was dead. So I am keeping the working games intact and mameing the third.
The place that I got the cabinets from had a cocktail in rough shape they were considering getting rid of. It had no boards, monitor, or coin door. If you are interested in that lead let me know.
