Polycrystalline Diamond sources?

[timtiminy]

Hi guys I'm looking to buy some PCD in the form of either powder or slurry/spray. I know Ken Schwartz sells the stuff, I was hoping to find a similar product for a bit less and maybe in powder form as to mix my own spray. I doubt I'll need much of each micron size. If you guys have any sources for suppliers that sell PCD in small quantities at affordable pricing I'd love to hear about them! Thanks!
