Razer Deathadder is one of the more popular mouse choices within your budget. It's a longstanding design that has been popular for several years. Personally despite their sketchy reputation, I have had good luck with the mouse that I bought from Razer. Lots of other good mouse designs as well, but this one is probably worth looking into although I believe it's an optic and not the same as a laser, I have heard that it is one of the most precise optics around. I don't have any personal experience with this model but that is what I know about it =).
