I've been told its like Formica brand laminate.. (at least here) only available through wholesale distributors. I'd talk to the company that specializes in selling wood to the custom cabinetmakers. To get my Formica, I paid the wood seller who then gave me a purchase order to pick it up from the wholesaler (they offered to pick it up but I was in a rush). In that case I was limited to full sheet sizes... 4'x8', 4'x12', 3'x10', 3'x16') etc.
If you want a smaller amount, are flexible about color and schedule, you may be able to befriend one of the local cabinet shops and have them get a bigger piece than they need on their next job and cut off and sell you the scrap (i.e. buy a 3'x16' when they need a 3'x10' and sell you the 3'x6' cutoff).
Just a thought...
