I can vouch for the Microsoft Sidewinder X8, although its not the most comfortable mouse I've ever held.
It never lags or has tracking problems, uses bluetrack so works on any surface, I tried it on my leg and it was perfect.
I'm considering replacing it with a G700 just for the comfort, but probably won't bother until there's a problem with it.
