The Razer Krait has on-the-fly sensitivity & an IR sensor, & is noticeably cheaper than the G5 & those other Razers. Though it's quite small/short, which I personally like but you may not - when I use one of the uni computers with a microsoft intellimouse the things feel huge!Well, on-the-fly sensitivity changing would be nice, 2 side buttons, optical sensor (preferably) and nice feet. Basically, my choice is out of the Razer Diamondback, Copperhead, Deathadder and Logitech G5. The Copperhead looks very similar in shape to that Logitech mouse pictured above, but the laser sensor is putting me off. Then there's the Diamondback, which is very similar to the Copperhead but with an optical sensor (great!), but the rear of the mouse is a lot shallower which, i fear, will mean i can't rest my palm on it. Also, both the Copperhead and Diamondback lack on-the-fly sensitivity changing and don't have very good feet. So this leaves me with the G5 and Deathadder. My current mouse, which is a £7 laser mouse i got from eBay sucks; this is the reason i don't really like laser mice, they feel jumpy and jittery and don't seem to track very smoothly. Anyway, since it's a similar shape to the G5, i think it would make quite a nice upgrade (although not being the ideal shape, and i'm still wary of getting a laser mouse again). So this leaves me with the Deathadder. Apparantly, it has one of the best sensors out there, but it lacks on-the-fly sensitivity changing and i've never used a mouse of that shape so i can't be sure i'd like it. Oh, there's also the MX518, which should be perfect (well, again, not the ideal shape, but i know i can stand it since it's similar in shape to the mouse i use now). You can change the DPI on the mouse, it has the side buttons, optical sensor, but lacks descent feet. I really don't know what to get..
