What is a good case for my black iPhone 4S?

I want a case that I can use everyday, has a nice style and can protect my phone from the average drop. I don't have insurance on my phone so I would like to keep it in a good condition (no scratches, cracks, etc)

I love my ballistic case (for 4s) It has a hard part and rubber part and a hard part that covers the back. The rubber covers the sides and corners as well as back under the hard part. It protects the glass while the rubber absorbs the shock of the drop. I've dropped my phone a few times and have been very grateful for the case.
