no, i've never owned an Xmen machine. i pretty much stick to the 79 - 83 era. Paperboy was an exception, took it in trade. Some games are very hard to restore due to lack of artwork/parts. I have a few games i've slowly collected parts for years, and still not quite there. I am anxious to restore my black widow to sell, but all i can find is a solvent jet printed Cpo, normally i don't mind that if done right, but it's predominantly black, and that just never looks right. I also need a marquee and they are rarely in good condition. Two on ebay last week, both in terrible shape. I currently have about 30 - 35 machines to restore and sell, and 5 i think i'll hang onto.
I have a babypac that i'm going to restore and heavily document, it should impress anyone. I'm going to reproduce the playfield, the plastics, rechrome everything, new cabinet, etc.
