I sold mine for $3400 CAN, around $2800 US. It was fully working, full leds and decent ramps, mountains. ( a couple of cracks ) Game had a few mods added as well. Playfield was nice, someone added a decal to the mine kick-out. Cabinet was painful to look at though. Topper was original and working, small wrinkle in it.
The market decided that's what it was worth.
