hi, next week is my birthday, and i think i want to get myself a new mouse. currently using sidewinder X3 for 3 years and has no problem until recently the mouse wheel button became very non-responsive.

basically i am palm gripper, my budget is less 200, i play game fps alot.
any recommendation for new mouse?
i current looking on roccat kova, kova[+], deathadder, g500 and ss kana.
also, taipan and sensei[raw] is one of my consideration (if no budget constrain )
so any advice on performance wise?

do you have any problem using it? my friend said that razer product always easy to broke but the customer service is very good
