Well I bought a gaming mouse recently, although I didn't want all the programmable buttons and went with something more simple. The SteelSeries Kinzu V2. It has L, R, Scroll wheel and DPI switch. The shape is symmetrical and the software has a setting for lefties. So if he likes all the bells and whistles it may not be a good choice, but if he wants something more simple as I did I highly recommend it as I love mine.
