Newegg offers the Cooler Master Devastator II LED CM Mem-chanical USB Gaming Keyboard and Mouse Combo in Green, Red, or Blue for $29.99. This $10 mail-in rebate drops it to $19.99. With free shipping, that's tied with our August mention as the lowest price we've seen. (It's the best deal now by $6.) The keyboard features mechanical-feel switches, LED backlighting, and laser-etched keys. The mouse features six buttons, an optical sensor, on-the-fly DPI settings (1,000/1,600/2,000), and rubber side grips. Deal ends October 11.
