NeweggFlash offers the refurbished Logitech G105 Backlit Gaming Keyboard, model no. 920-003371, for $21.99 with free shipping. That's the lowest total price we could find for a refurb today by $10, although we saw it in July for $2 less. It features dual-level blue backlighting, ambidextrous design, an 18-month battery life, and fully programmable G-keys. Deal expires September 28.
A 90-day warranty is included, although it's unclear who backs it.
