Jungle Lord went from a game no one cared about 3 or 4 years ago to a game that brings decent money these days. We have had one in our collection for years and it has always been one if my wife's favorite machines. As far as price with everything missing that seems on the high side of logical but with a complete nice playfield & decent cabinet I don't think the price is insane.

Fixed up with a decent backglass and working it should be a $1600 to $2000 machine in today's market.

Your location will also have some influence on what value to place on it.
