Newegg Flash offers the refurbished Razer BlackWidow Ultimate 2014 Wired Elite Mechanical Gaming Keyboard in Black, model no. RZ03-00384600, for $49.99 with free shipping. That's $11 under last November's refurb mention and the lowest total price we've seen for it in any condition. (It's also $33 less than you'd pay for a new one today.) It features individually back-lit keys, on-the-fly macro recording, five extra macro keys, audio-out and mic-in jacks, and 1GHz key polling. Deal ends May 12.
Note: A 90-day warranty applies, but it's unclear who backs it.
