I remember that Firepower on eBay, it was also in pretty good shape playfield wise. You have a nice original backglass, nice original playfield (with I'm sure some cupped inserts). As mentioned, 1000-1200 would be a good price for you in non-working condition. I honestly think it would be a tough sell for a non-working one at 1700, but hey, I suppose you can never go back up. And if you list for 1200, I'm sure someone will offer you 400 . On eBay, you can also list as Local Pickup only with no shipping option...

As a disclaimer, I already have one, so I'm not trying to talk you down in price. I bought mine in the area working for 700 3 years ago, albeit with a much worse playfield/backglass combo. But of course times/prices have changed...
