Now I don't know if your male or female.
In case you are female, or you'r a guy with very slim hands. I can only reccomend razer - and it's exceptional good too if you'r left handed.
I am left handed, and it took me 2 years to find a mouse that suit my hands. Logitech makes some really good ones, however they are way too big to my tiny hand, so I cannot reach the buttons.
Razer copperhead, is awesome though, despite the 7 buttons on it. But I've hotkeyd them with an alt+ as well
