I was in on a group buy of the same size/type of glass last year and it was a complete success. Hope you get it done, because for the discerning collector it's well worth the price. My HUO Paragon looks 100 times better since I got the PDI glass.
Gweem, that's a real bummer about the Gottlieb glass. I found this thread because I'm looking to buy a sheet of PDI for my recently restored Spirit. Dang!
