My current Microsoft wireless optical mouse has just died. It lights up but wont connect to the reciever and then after 3 mins goes into power save and switches off because no signal so its fucked

Im now looking for another Wireless mouse but i started to play alot of games. The only wireless gaming mouse that i know of is the Logitech Cordless G7 Gaming but its £50

Would you pay £50 for this mouse : http://www.logitech.com/index.cfm/pr...ONTENTID=10716

Has any one used one, or know of a better product on the market?

What you think?
