Got a question for you Mark... How high is the control panel? From the video, it looks like the control panel doesn't quite come up to your belt when you're standing in front of it.
I've been fiddling with drawing up plans for my own spinner, and compared to 1-up's and Frosty's and from what the video shows of yours, it looks like mine is going to be ungodly tall... the top of the monitor bezel is at about six feet, and then the marquee would be above that. But then I'm trying to set the CP at about 37 inches, the same as a pac/galaga cab.
