I'm using a regular razer Lycosa and what can I say... It's just an awesome keyboard. The only thing I noticed is after over 4 years of, lets be honest, heavy using the rubber on the W key wore off a little.
Also, if you are a tidiness freak then it's not a keyboard for you. The reason is simple, the area around the keys, even tho it looks beautiful, can get stained with finger prints quite easily, which are much more visible on black, reflective surfaces.
Other than that the keyboard is fantastic, very comfortable, looks sick, and the backlight is a nice touch.
When it comes down to mice all my friends reccomend Deathadder for FPS games, but all other mice are top notch too. I personally use a Logitech G9 tho.
