Razer. They have a pretty good reputation for making good gaming peripherals. Though they are also notorious for have very poor quality control, and insane markups. A mouse pad for $60, it doesn't even last a year. I think the worst thing though is a keyboard I bought called the Lycosa. It was very expensive and I'm glad I was able to sell it. I wont get into specifics, but it's easily one of the worst keyboards I've ever played a game on, not because of preference, but because of how it malfunctioned (design flaws not broken keyboard).
