Quoted from Dent00:There was a guy at the Texas Pinball Festival selling glass for $25 per sheet (cash).
Or 5 sheets for $100, a great deal. I've only bought standard glass from him. Nine out of ten pins I buy have noticeably scratched glass. At $20 I just replace it.
I did have to pay about $60 locally for my tempered Paragon glass though. Still a good deal.
