Mouse recommendation :)

[Sudden]

Currently have a Razer Copperhead which i've been quite happy with. The scroll though has been acting up despite some cleaning so since it has been a few years, thought I would get a new mouse.

Will be used for light gaming mostly, but since i've gotten so used to the 2000 dpi on the Copperhead and I use that on the max setting, a minimum of that is needed. It also must have two buttons on the left hand side like the copperhead, or something as conveniently located. They are mostly used for 'back' and 'forward' in firefox, general windows stuff etc. (used for jump and crouch in gaming, but not as much).

Budget is about 40 pounds I suppose, but am flexible.

Deathadder seems to be a pretty clear winner here then. Mx518 was also a possibility since people recommending it had already tried copperhead but if the it is a fair bit slower than the copperhead, then i'd rather not go there since i've gotten very used to the 2000 on the copperhead and can't imagine going back to a slower mouse.

The saitek looks a bit too wierd for my taste. I want something relatively normal looking

I've heard some good things about the Logitech G500 which I haven't seen mentioned here much. Is that something to consider or is Deathadder far better?
