I would buy backglasses

Shay Arcade Group and Homestead all use silk screening just like the originals. Bgresto prints on a label and uses a process to adhere the label to the backglass. It’s a really nice result, but not as good as silk screen. I’d buy a new backglass from Shay, Homestead, Greatwichjohn or Cpr. If they don’t make a title that you want then I would order from Bgresto. This accomplishes two things; gets you your backglass quickly, and reduces the number of Bgresto backorders so that people that have to order from Bgresto, as he’s the only one that makes many titles, can get their glasses quicker.
