Do the exist? Every gaming pad I've ever seen was designed to be used by a right handed person, however I stopped looking a few years back and they now have ambidextrous gaming mice, so I thought it would be worth asking.
@ETNiES: I use the Copperhead too as it happens (love the onboard profiles, I just plug in to any PC and use left handed - win). Maybe all the lefties (and the anomalies like me) should join up and make our own mouse and game pad company
