Newegg offers the refurbished ASUS 802.11ac Wireless Dual-Band Gigabit Router, model no. RT-AC68R, for $114.99 with free shipping. That's $77 under the lowest total price we could find for a new one. It features data transfer rates of up to 1,300Mbps and USB 3.0.

A 90-day warranty applies, but it is unclear who backs it.
