I just bought a RAZER COPPERHEAD mouse last week (TEMPEST BLUE) to match my PC rig, and after using a MX1000 laser for 2 years, I can say I don't care for it myself.
At 2000 dpi, it is way too sensitive for my gaming style, and the mouse is so light compared to my logitech, that i am all over the place with it even at 1000 dpi. It looks super cool with the lighting of the siderails and scroll wheel, but I am just an old dog that can't learn this new trick (super sensitive aiming that is).
If anyone here is looking to buy one of these Razer gaming mice, I will sell you mine at a bargain. I am a long-time ebay seller (1999) with 100% positive feedback with over 20 auctions. I would be glad to post my item for you there or sell direct if you want to avoid fees on both ends.
If you're interested, send me a PM and we'll talk.
PS- unique feature of the razer's... they are uniform in design so they fit lefties or righties the same.
