Sold my Pinbot and bought this locally.  It didn't work.  It was the dirtiest pin I've ever seen..  The first pics show how much dirt was on it and the 'unusual' repairs.  It's surprisingly in very nice cosmetic shape under all the crud.

I gave it a quick clean (center of playfieldf and ramps) and fixed all the issues.  I replaced all the dead feature lamps (27 of them!) It now works 100% and the kids really enjoy playing so I'll shop it out  later.  Most of the GI is out but it's burnt bulbs and not a GI issue - I checked.
