I need a new mouse since my 6 years old logitech dual optical died one me =(

I dont really care about the negative accel, dpi and such as long as it is not worse than the dual. However, one thing i can not live without is auto left button click function. I know this can be done by any macro software but there is this one game i keep spamming about and its EULA prohibits software altering with it in any way, attended or unattended.
