I have figured out why I enjoy looking at WOZ so much (not my favorite to play though). I was just at my monthly Pinball group (Shout out to Buffalo Pinball!) and our host this month had a LED'd Metallica pro with this Glass on it. It makes every other game pale in comparison. If you are to add one mod to your machine that you will never question I think this would be it (Probably piss you off though seeing as you will want it for every pin thereafter). Hope this advice can push someone over the edge if they were debating on it as it isn't cheap.
