I use and like my iLap. Which matches the MacBook Pro perfectly, with it's aluminum finish. It lifts the rear of the MacBook Pro by a couple of inches too. But unlike some other products, you can still use the built-in keyboard.
The iLap I have, I brought for my old 17" PowerBook, and it fits my 17" MBP perfectly. My PB ran a lot hotter than my MBP (I have the 2.33 GHZ MBP), the MBP is a very cool laptop. The latest generation may run a little hotter though?
