Someone's trying to sell one locally in working condition with an above avg playfield, poor guy can't sell it. He originally listed it at 1k, and it's been dropping $50 every couple of weeks. Down to $750 now and it's still listed.
The biggest issue with yours though is that it doesn't work. You'll get a lot more for it if you clean it up and fix it. In a non-working state I'd be surprised if you got $300 for it.
