dont get gigabyte M6800!!! It sucks. When i hold the mouse, i cant even control it properly and the design make my hand numb after using it for a while. Bought it at RM50 but now price down to RM30. I'm currently using Logitech G5 and live very good with it. If you guys have the budget, get G5 but hold the mouse and see if it fit your hand before buying.
