Id suggest the Logitech G300, its $30 and here are a list of some features
http://www.logitech.com/en-us/product/gaming-mouse-g300?crid=825Customizable LED colors with game profiles
4 Side buttons (2 on each side) + 2 buttons in the middle
2,500 DPI (very good for gaming)
Macro support, you can make a rapid fire if you want
And well thats basically it (there might be more) besides having a great mouse for $30, I have the mouse and I have upgraded to a g9x but honestly I would use the G300 for the feel, it fits perfectly in my hand and its for left and right handed people.
