There are many companies that will sell cheapo wafers. You can even
buy them on e-bay. I have bought dozens of 4" wafers for very
little. I still have a bunch of em but I coated em with various stuff.

Wafers are cheap for being single crystal material, truly amazing. I
bought some ground to be .050 mm thick and 3" diameter, really cool
cuz they will bend to a 2" radius of curvature. Orientation was
Si(111) whereas normally what you get is (100) in this thinness.
