I have 3 repro backglasses from BGresto. They were glasses that Ron Webb and Shay weren't making and Mayfare did not have, so I appreciated a high quality product being available. I think the longest wait on one took about 4 months while the other 2 were around 3 months. I understood that going in and was not in a rush, so it wasn't an issue for me.

Yes, light transmission through the glass is a little less, but I either got used to it or went back to using 44 bulbs behind the glass. My machines are rarely on for more than an hour or two and not every day, so I'm really not worried about heat degradation (in my lifetime anyway).

I'm just glad the option is out there!
