try www.freckleface.com I bought a 4 by 6 piece of polycarbonate 1/2" for around $220 shipped. They say their polycarbonate is like 150 times stronger than plexiglass (or acrylic) and plexiglass is around 10 times stronger than glass. I am using this for my wet/dry (cut up of course). They say that you could throw a brick off of polycarbonate and it will not break.
