Can someone recommend a good source for pattern board in small quantities? I need it ~3" thick, ~6" squares, and need to get a good surface finish with a 1/16 ball end mill on a CNC.

All my searches yield manufacturers of the stuff, but I cannot seem to find retailers, even on eBay.

Thanks
Scott

Are you looking for something like REN urethane tooling board?
If so, where are you located?

Yeah - REN is just what I'm looking for, or an equivalent. I am in Binghamton NY.
