Gaming mouse with a 'sniper' button? (Like the R.A.T.)

[joxang]

One of my favourite features of the RAT series is the precision aim button which toggles DPI down a notch when pressed, making it really easy to get headshots. DPI is then restored as soon as you let go.

Does anyone know other mice with this feature? I'd rather not get a RAT due to its sensor issues.

Yeh the 'toggle' thing is what I'm looking for. If you're in the middle of an FPS there's no time to stop and switch up and down...I wonder if saitek have it patented.

What sensor issues?

(I have a RAT7 and have experienced no such problems)

Sensor failing, erratic tracking (cursor gets stuck, have to unplug and replug). I know a couple of people who've had to RMA so might be a bit biased by that but come across forum mentions quite a few times so it appears a common problem.
