(sorry for late reply)
I said that about my old mice at 3200/3600 dpi but after using for like 2 days i was used to it and no one could use my mouse at lans! I had max on windows mice options and on the mouse, which is alot compared to my mates with alot less dpi (1800 ).
Right, the x8 seems great but as mentioned my budget is £30 and that mouse is around £49(at novatech,cheapest including del), now the problem i have is i can and cant justify it. I had a g15 and sold it as im downgrading most things and want to save on cash so spending a similar amount on a mouse as a keyboard seems to much for me, however i do love the mouse and i really want it which is why im still debating about getting it!.
Had the fireglider, good mouse but i felt like a change and was planning on moving to wireless (that didnt happen!).
G5, dont like the design scheme and seems a bit expensive for what it has (wired/2000dpi). Mx518 is great but my mate has it and so id want something different and also dpi could be a bit to low for me!.
Thanks for all the suggestions so far, more choice is appreciated!.
