Saw this on Dick Smith and looks like a good price according to PriceSpy.
Description:
Designed to keep either hand happy. Soft side grips and a comfortable shape — so you’ll feel good, even after long hours of use.
You can go for a year without battery hassles. An On/Off switch and smart sleep mode extend battery life, while an indicator light eliminates surprises.
You get the high quality and reliability that have made Logitech the global leader for mice — plus a three-year limited hardware warranty.
Enjoy precise clicking and pointing—on surfaces other optical mice can’t handle — while navigating your favorite websites thanks to Logitech Advanced Optical Tracking.
