Recommendations for wireless optical notebook mouse?

[Naruto]

Hi, I'm in need of a wireless optical notebook mouse. I know that logitech/microsoft are good ones, but how about others like a4tech or itronix lynx? I need one with good performance, good battery life (preferably using AA batteries), and on/off switch. I saw the new logitec V500, which is sweet but haven't seen it for a good price yet.

I got the v500. I love it as much as my mx700.
