I use razer death adder. It fits very well in my hand, and I have mapped the side buttons to PgUp PgDn because the scroll is so slow it is unusable (MX Revolution had the best scroll wheel ever that moved from discrete to freewheeling on the fly, sadly they decided not to implement the technology any longer in any products). As usual with razer build quality is between mediocre and crappy.
