I still like my Razer Copperhead that came out like 4 years ago. 2000 dpi, 7 programmable buttons. I don’t remember how much I paid for it, got it on a woot-off, so probably like $30.

Now I’d grab me a Razer Naga if they made the damn thing in either a lefty or ambidextrous shape. 5600 dpi and 17 buttons is freakin’ sweet! Oddly enough, I am a righty, but due to threats of death if I didn’t put my dad’s mouse back after I was done, I learned to use a mouse left handed. I can use it both, but prefer lefty since I use the arrow keys for things like moving in the direction the arrows point. =\
