I found the game in May of last year. Here’s the link from then.
I’d love to have one, but A) I don’t have the room for it; and B) probably out of my price range. I did find a countertop model (also Mills) a few months ago for about $450. Tempting, but still more than I’d like to spend. If I knew anything about building electrical things, I could probably make one for a few tens of dollars. But I don’t. I need to find a hobbyist who would do it.
