My favourite computer mouse

Has these features:

• Low latency
• Cheap, $35USD for the black version
• The right number of buttons for me
• Lightweight
• AA battery powered - so unlike other mice with built in batteries which will eventually die completely, this is future proof!
• Modding community - mainly to make it lighter
• Does not use bluetooth
• USB receiver stored inside the mouse. I was infuriated by my previous mouse, a G703 whose receiver I constantly feared losing.
