Newegg offers the refurbished Corsair Vengeance K70 Mechanical Gaming Keyboard, model no. CH-9000011-NA, for $77.99 with free shipping. That's tied with our mention from last month and the lowest total price we've seen. (It's $45 under the best deal we could find for a new one.) This well-reviewed keyboard features Cherry MX Red switches, a removable wrist rest, customizable LED backlighting, multimedia controls, and optional textured WASD and 1 to 6 keycaps. Deal ends May 25.
A 90-day warranty applies, but it's unclear who backs it.
