$4500 would have to be near-CQ with a green & clear hologram.
As Donjagra mentioned, $2500 would normally get you in the door. $3000 would be a decent game with some issues.
Game is prone to front cabinet fade; when I was looking for one most had front fade. I've attached a pic from HEP showing how nice they look when they're unfaded.
The Hot Pink PFs are more desirable and look cooler IMHO.
Sun Process PFs are more durable/desirable than Lenc Smith PFs. Look for the letters SP vs. LS under the apron by peaking in from the left side with a light. Watch for planking on Lenc Smiths.
One of my absolute favorite games. Quite difficult; great longevity.
Post some pics of what you find and we'll let you know what we spot.
