Looking for a sensitive mouse for a long term relationship

I've found selecting points in a sketch sometimes frustrating because my pointer isn't sensitive enough. It almost seems to want to jump from pixel to pixel and not easily select one spot. I have to carefully "aim" my pointer to pick what I want. Slows me down and causes my wrist to tense up.

Is there a mouse that is more accurate? I've tried all the mouse settings to no avail. I'm currently using a Logitech Inteli Mouse (along with a Space Ball). Anyone use a gaming mouse; Razer Mamba or SideWinder?

Thanks,
