Top choice in ultra thin case for 3GS

[MTHall720]

I'm trying to find a good quality, very thin and light case for the 3gs. I could settle for a little bulkier though if the looks are really hot.
Any advice in acrylic, plastic, or thin metal?

When I had my 3GS, I really like the Incase Preforated Snap:
