I never used the Copperhead but I have used the Logitech MX518 and G5 and those are excellent. I hear they are better then the Razer. Widescreen gaming is really cool. Some games like HL2 and CSS work incredible with it, but some games you need to change some things to get it working right. I plan on getting a 22" widescreen monitor this christmas because it looks so good IMO.
