Yep price is condition dependent.
Look for playfield wear between the 3 bumpers, inlane ball drops and chewed out eject holes above the slingshots.
Hard to find with nice cab art, and the side rails oxidise easily.
$2k or less and you're doing OK i reckon. Interesting title as it was considered a dog on location and has had a pretty ordinary reputation up until a couple of years ago. Must be the Mario/Nintendo retro thing.
It's a fun game, if not a tad easy.
