Best mouse?

[Nomad84]

Is the MX1000 still the standard for the best mouse for poker? Has anyone compared it to the G7? Any others I should be looking at? I noticed on the Logitech site that the G7 has changeable batteries that last for about 10 hours of use each. What is the battery life like on the MX1000, and does it ever affect your ability to play? It doesn't look like you can swap batteries on it, so is there ever a need to stop what you are doing so you can recharge it?

Thanks!
