If your interested, I got a new MX1100 for sale. Performance/button-wise, its on par with the Revolution.
I am currently using the same mouse paired with the Wave Pro; the mouse fits like a glove. I think its much better than the Revolution since the batteries are replacable. Just grab a set of Sanyo rechargable batteries for it and your set.
Here a link to my post, let me know.
Thanks.
