What case for your Nexus S 4G?

On my Nexi I'm using cheap cases from Amazon. They are very snug fitting but holds on to the phone extremely well.. You might want to be careful if you have Invisible shield or any other screen protector because I learned the hard way that just putting on the case is very very tight.. But I would still recommend this to anyone who wants a cheap but good case..
