Please offer separate restoration check!

I sympathize with duckduckmike's gloom on getting an SA grade on his X-Men #3. For all the money we collectors pay to CGC, surely they could offer a service where they just pre-screen a book for restoration for, say, $10 a book, and then let you decide if you want to pay the extra to have the book slabbed. It seems impossible to avoid sending restored books to be graded when CGC's techniques for detecting it are so much more advanced than the average collector's. Of course it's not in CGC's interest to offer this service, but I bet if someone did offer it they could make a packet. Classics Incorporated appear to do restoration checks, but this is only if you're getting a book pressed as well. Does anyone know of a reliable place to get books checked for restoration, prior to sending them to CGC?
