Prices for this title are a moving target. Five years ago dealers were selling IJ for $5000 - $5500 with faded cabinets, poor shop out work and flipper wear. I guess due to the saturation of imports, the price may have dropped somewhat, but collectors still view a restored machine (New Decals, no wear on playfield, gold trim and ramps) as a high end pinball that can fetch $5000 +.
As soon as you see an IJ with new cab decals, you can add $1000 to its value right there. Brett - That brings your machine in line with a $5000 + pin.
