Do NOT, go with the steel series mouse. I got one as a gift last Christmas and, by February, of this year the 'metal' finish on the right click had worn off and the button has started to rust. No joke.
Now, almost a year into owning the mouse, half of it is covered in packing tape to keep from making my hand itch due to the weird metal to plastic texture all over it.
This year, I will be asking for another mouse, or buying one with Christmas money.
Other then the what I had listed, it's really responsive, high DPi for quick response and the software is really macro friendly and easy to use.
Over all, Naga all the way.
