Quoted from FrankJ:
With all of the technology advances, I can't believe that no one has come forward with a better business plan to compete with him.
Not quite sure what you mean by this. BGResto has the technology. Direct printing on glass is just about as modern as it gets, but it's not the best as far as clarity and translucency. Ron Webb does it old school with screening and his are the best anywhere...indistinguishable from original.
That said, I don't think anyone making backglasses has quit their day job and just sits around cranking them out. Shay has a limited run of glass as does Ron Webb and John Greatwich. BGResto has the largest selection of already done artwork. Recreating new art I'm sure takes a looooooong time. I figure if he gets 300 requests for backglasses, and he can print 3 a day, I'd guess you'd be waiting 3 months minimum. Seems reasonable.
