In my opinion, Logitech makes the best computer input devices, period. They pioneered both desktop laser mice and wireless mice, paving the way for the amazing MX1000 to come to fruition. Unfortunately, the MX mouse series is rather expensive, and the MX3100 isn't exactly easy on the wallet, either. Finally, there is an affordable, cost-effective solution: the MX3000 Laser Combo. This nice kit combines the MX3000 keyboard with the MX600 Laser mouse.
