What Is The Best Iphone 3g Hard Case With The Best Protection But Has A Simple Design

I am looking for an iPhone 3G case. I want it to be a hardcase with as much shock protection as possible, in case I drop it. I don't want there to be a cover built into the case for the screen because I prefer having just a film on it. Also, I would like the case to protect the buttons and the screen as much as possible. Also, I am looking for a case that is simple. I hate fancy cases. Thanks.
