One thing I would add about the G9x is that I have found the weights to be a bit useless for me. I use mine with no weights in and there is only one man alive who can use it with all 4 heaviest weights in, and that man is Thor.
By budged I am assuming you mean budget?
I have used the Razor Deathadder in the past and can recommend it. Might be a bit pricey at roughly £40. Logitech G9x is also decent and probably a similar price. Both with good DPI, mouse buttons 4 and 5, and perform well.
why is it hakank that you seem to keep making threads, you may seriously be looking for a mouse but was some of the other ones necessary? and you seem to keep making non constructive posts across the forums.
