A wireless bluetooth capable mouse?

I'm fed up with my "mighty mouse" for my imac...the scroller has broken down so many times, and I've had to replace it twice. I'm looking for a similar mouse with bluetooth, and something that will not require a usb port, also more ergonomic. Any suggestions would be greatly appreciated!
