For those of you unfamiliar with mcmaster carr, here is their web site. They are not the cheapest place but have almost anything and will sell to anyone and do the onesie twosie stuff.

An extruded, which is more easily thermoformed, and a cast sheet - which is supposed to have superior optics but harder to form.
