I had Meyers decorative surfaces fabricate them & install for me. It was pricey...about a grand for the 3 countertops the sink and the sink cover.
They sell them in sheets of 3 x 5 for about 300 each (here in Wilmington). Cheapest product I could find was going to be about about 500 for the job. I figured the extra 5 was worth the pain and suffering for a pro install (plus I don't have the pro tools to do the edges nice and tidy).
These are not corian btw. They are Formicas solid surface line. Same thing...different colors.
