Yes, it's nice to know that many sc2 players are around here.
And also, I've saw that boxer uses razer deathadder as his mouse, and someone mentioned he plays with black widow too, but I don't know exactly if this is recently or not, I know deathadder is from old times, due pictures, but idk about the keyboard, probably he uses both now, since Razer sponsors him and all the SlayerS team, but who knows.
All the EG team uses SteelSeries material, since they sponsor them, I know that iNcontroL uses a 6gv2 with black switches. And there was a guy spoted at MLG using a filco, but I couldn't recognize who was exactly, by the looks I think it was TT1
