The Razer Onza controller for the Xbox 360 comes in two versions, a Tournament edition and the standard edition. Both controllers have the same basic features: a precision D-pad, enhanced ergonomics, two programmable buttons, and a 15-foot long braided cable. The standard version features a textured surface for better grip while the Tournament edition has a rubberized body to give you a good grip.
The main difference is that the Tournament edition features adjustable resistance on both analog sticks for the best precision. The tournament edition is so in demand that it is already sold out for pre-order at $49.99, but you can still get the standard version for $39.99.
