You would also need a decent mousepad. Steelseries QcK should be around 800. Mouse is all about preference.
MX518 is a good mouse, although a bit high. Comes with adjustable weights and on the fly dpi changer.
Microsoft Intelli 3.0, great mouse, very comfortable, around Rs 1900-2000, no dpi changer, no adjustable weights.
Razer DeathAdder, great accuracy around 2.5k to 3.5k (1800 dpi to 3500 dpi), comes with all bells and whistles, although some user reports the double click issue after some time.
