Before I could afford pinball machines I thought of taking the $30 CL Pachinko machine as a fix. Asked online if it plugged into the wall, they said for a few little lights.
Having little to no electronics in the equation wouldn't be as cool for me. Glad I passed on it. On the other hand, I was sad when I figured out EMs don't have attract mode and I was set to buy one, but I got over that and now love EMs and collect them almost primarily. I have come to appreciate the lack of an attract mode on these games and still love them on the newer machines, of course.
