Bought my first pin! Nicely restored Williams Laser Ball. Whole family is enjoying it. My question is-How important is the cash box to all of you? This machine is missing the cash box. Have it on free play so it doesn't really matter. Do most of you leave your machines on free play? Mostly just my OCD needs the cash box. Saw one on ebay for $45. Saw a plastic tray cash box there too for $9. If I switch it to coin play then I can have some more sounds coming from the machine as well as attract mode. Thoughts? Opinions?
