Just bought the VX Revolution mouse from Tiger Direct. What an EXCELLENT mouse. I have no gripes or anything about it. Only takes one battery. VERY responsive. A search feature which allows you to highlight a word and then it automatically is searched by Google or Yahoo! A magnify feature which lets you zoom in on a website or word document. The clickwheel is the best part. There are 2 modes you can choose from. Hyper fast or precision. Precision has the clicking that we're all familiar with when we scroll through websites. Hyper fast has no clicking, so you just spin that baby and it will keep going for a good 10 seconds. Great for scrolling through huge documents or finding an old email. Overall it is the BEST mouse on the market in my opinion. Paying 20 bucks or whatever it is more for the higher end one is not worth it from what I've heard. And for $30 at Tiger Direct it's great, that's with the $20 mail in rebate.
