I'm using the razor pro mouse.
compare to mighty mouse, I dig in to this mouse more than the MM. Reason is it's design to fit in to the palm of my hand and it's white in color.
i like the smoothness of navigating with it. and it's suit my daily use of in 3d modeling and animating.

if u buy the mouse alone without the pad. it's about RM220. not too bad for a professional mouse.
