Copperhead and Deathadder served me well for my later FPS years (I can't remember what I used on Ten back in '96). After that the original Naga was good though always felt the side buttons weren't pronounced enough. Then came the Naga 2014 and not only did they fix the buttons but it's just such a nice mouse in general. It's got great size, control, natural weight, and the texture is a bit erotic.
I paid full price for it at launch and it's been one of my top 5 all time PC peripheral purchases.
EDIT: I was going to take a picture of mine with the lights turned off, title it with a caption about 'Matte Black'
Then I thought I'd just pull a picture from Yahoo images with a search on 'Naga 2014 lights off'
One of the first results was this.
Hey baby, wanna see my Naga?
