I'd strongly recommend the Steelseries Sensei, I believe its about 130$ which is slightly more than your willing to pay, but it's a really really good mouse. It was the first 'gaming' mouse I haven't regretted it at all.

The mouse itself I find is very comfortable to use, my hand/palm fits perfectly over it. The buttons on the side of the mouse have come in useful for easier to reach hotkeys, this is kind of a null point though because most quality mice these days come with that i believe.

Another thing thats really good about the sensei is how much "stuff" you can customize, be it the colour on the mouse, to having 2 different dpi/cpi settings per profile. You can fiddle around with acceleration/deceleration if you want to, amongst loads of other things, and this can all be done within the mouse just using the wheel and a few extra buttons.

Things I dislike are that occasionally it sort of spazzes out and the mouse becomes slow, I'm not exactly sure whether this is my mouse pad not being clean though =p.

Other than that it's a great mouse and I'd strongly recommend it to anyone.
