We used to make cutting boards out of the sink cutouts and give them to people when our installers showed up. We had thousands of them laying around the shop. I bet if you found a local fabricator they'd give ya one cheap.
My countertops in my TT are LG Hausys HiMacs material. Not sure if FR used them for all of their tops though. It's the same material as Corian. If you have an area you can see under your tops it will have the name printed on them. (saw the underside of mine in the outdoor kitchen)
