Gaming mice aren't the cheapest, so the Logitech G300 is the next best option for those looking for something to start off with.
The Logitech G300 is a basic gaming mouse that has all the standard features. It's ambidextrous, so left or right-handed, everyone is covered. There's nine programmable for users to personally customize to their liking. The on-board memory profile will allow up to three different customizations, which is perfect for multiple players. The G300 also has a 2500 DPI optical sensor, which provides a quick response rate.
The Logitech G300 may not be as advanced as the Cybor R.A.T. 7 or anything Razer puts out, but it's a good gaming mouse to start out with before you move on to the big boys.
