Deal Frenzy via eBay offers the factory-refurbished D-Link AC750 Dual-Band 802.11ac Wireless Cloud Router in White, model no. DIR-817LW, for $19.99 with free shipping. That's $10 under our mention of a new one from January and lowest total price we've seen in any condition. (It's $3 under the best deal we could find for a refurb elsewhere.) It features both 2.4GHz and 5GHz bands, a data transfer rate of up to 750Mbps, and five Ethernet ports. A 90-day D-Link warranty applies.
