It's not about class, it's about personal preference - I've used over 5 different mousepads and finally stuck with the Fatal1ty branded one. While the Razer Mantis pads are good, it may not necessarily suit everyone.
Evil, first you gotta decide whether you want a cloth or a plastic/glass pad - cloth is a safe bet because it will work with any mouse. Other pads like icemat, ratpadz, steelpad will only work well if your mouse has teflon feet/skates.
