I love the Speck cases ...you can order on Amazon for a bit less $
Finally Apple endorsed Speck cases as well.
They look really nice too.
I have a Speck case waiting for the arrival of my phone that I don't have yet
I would recommend an Otterbox case. The new Otterbox cases for the iPhone 5 that have the rubber surrounding it, seem to be made with a better material compared to the iPhone 4 cases. I got the Otterbox defender case for my iPhone 5 for $32.00 on Amazon.
I also have the otter box defender. Is a great case I had it with my Droid x2 and now my iPhone 5. I bought mine of amazon for $32. Very good protection for the phone. I highly recommend the otter box defender.
The otter box commuter case is great alternative to the otter box defender if you don't want too much bulk on your phone or pocket. Plus its $10 dollars cheaper. If you go to Amazon.com you probably get it for cheaper there.
