I have a chance to buy a puck-man( not pac-man) cocktail for $125. The owner states it works but has no sound. It has many scratches on the plexi and part of the coin mech is said to be missing. I saw a picture of the screen and it looks pretty good, but who knows until I see it in person. My question is it a good price and is sound a hard fix. I have no ability as far as that stuff goes, but if it sound like loose wire or something I would give it a shot. Any advice would be great. Thanks!!
