I've had the opportunity to shoot at two Star Jets...
The first was on ebay about 5 years ago; not working, worn to wood on the playfield, horrible flaking, pick up only - sold for a little over $650
The second was a collectible auction earlier this year; powered on but would not play, dirty and worn but not in horrible shape - my high bid was 1600 and I did not get it.
I wish I would have found your Star Jet before it was destroyed for entertainment, would have easily paid well to grab it in working shape.
Someday...
