I got the Griffin's 3-finger double corona case over a year ago and I still use it daily. It's awesome and goes well with my CF Palio!
I believe I got mine from egars.com.
Also note that there are two different patters of Carbon Fiber Griffins cases. One is just a diagonal and the other is called quardrangle (???). Or something like that. The diagonal is easiest to find and what I have. I also think it looks the best.
