Another source of corian you might want to check out is the Habitat for Humanity stores. My local store had a bunch of demo countertops from Lowes that were donated when they changed their displays. They weren't much use for anyone else, as they were short and had a sink or stove opening in them, but they yeilded about a 2 x 3 section from each side. I got quite a bit for $10, and it goes to a good cause.
