My buddy and I each bought IJ more than 20 years ago. I paid $1400 for mine back then (have since added ColorDMD and other stuff). My buddy just sold his IJ for $6800 (no ColorDMD) to fund his '71 Ford Pantera restortation. I told this to my wife to show her how the pinball hobby can hold its value. Now she wants me to sell my IJ and some of my other games just for the money.
So much for the point I was trying to make winding up biting me in the ass. I hate that.
