I know that a lot of the Quake Live players use mice with very accurate tracking sensors (G400, WMO 1.1a, IMO 1.1a) etc... but are there any people who have good accuracy with very poor mice:

e.g Logitech M100, Basic Optical v2.0 and any cheap optical that has a poor sensor in it.

I want to ascertain whether its important to have a gaming mouse and whether it is necessary for aiming well at QL.
