First, uninstall the Logitech Control Center software and driver. Download SteerMouse ($20) from
VersionTracker or
MacUpdate and use it. It has controls for fine tuning cursor behavior.
If the mouse is wireless bear in mind that the use of microwave ovens and some portable phones will interfere with the mouse causing jerky cursor behavior (and loss of wireless service as well.)
To answer your other question the two best mice are either Logitech's VX Revolution and MX Revolution. The former is a notebook model while the latter is a desktop model. Neither use BlueTooth.
