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.
