I've got the Lycosa keyboard but with the Naga mouse.
I like the fact it's backlit, the travel and feel of the keys I find suits me well, haven't really played with any of the profiles yet.
The Naga was a complete nightmare when I first got it, but that's due to me going from a 600 dpi mouse to a 5400 dpi mouse with 1Khz polling. I couldn't keep it off one edge of the screen.
It's good for WOW which is what I use it for with the assignable buttons down the side, although I have turned the lights off as it's a total distraction when you're having to look to press the right button from a selection of 12.
