I have a Williams High Speed available in So. CA. I just shopped it out and it's playing fast and working 100%. Cleaned and waxed the entire play field after removing top side parts. New rubbers, good plastics (only 1 minor chip), all new GI bulbs and flashers, all correct hardware, some new star posts, new beacon dome.
The cabinet needs to be repainted - lots of dings, scratches, gouges and paint flaking off from sun damage. The stencils are available for those looking for a project. The backglass is in excellent shape (with some fading), New onboard battery holder and the game is saving high scores. This is a players game - not a museum piece. The play field has wear as is typical for this title but I've seen other HS's in much worse condition. Delivery is available in So. CA for a small fee. Asking $1500 (or make an offer).
