Non Glare Acrylic for Framing

[boBQuincy]

I do my own matting and framing and always use acrylic instead of glass. I have been looking for some non glare acrylic in sizes from 11" x 14" up to 30" x 40" but have not found a good source. Most sources either want way too much $$$ or want to sell a case.

Does anyone use non glare acrylic and have you found a good source?
