G'day Sever! (long time no see, mate)
I've gone from the nastiest al-cheapo USB mice, to my most recent about six months ago that cost about $40 AU off ebay. It's a reasonably sturdy Logitech Mx-518, which I must say from personal experience, has probably been my hardiest mouse in terms of longevity and capacity to take punishment under times of duress.

I haven't gone yet to fully wireless as my brother has though, as I'm not real keen on the idea of my mouse suddenly stopping dead in the middle of a game.
I quite like the browser back button my mouse (which I've got used to) and the ability to increase the dpi. But in any case, Bungleau has provided sound advice!
