Newegg offers the Corsair Vengeance K65 Mechanical Gaming Keyboard in Gray, model no. CH-9000040-NA, for $49.99 with free shipping. (Amazon charges the same.) That's tied with our mention from two weeks ago as the lowest total price we've seen. (It's the best price now by $18.) It features a short-body design, aluminum chassis, Cherry MX red switches, and 100% anti-ghosting with full key rollover on USB.
