Newegg via eBay offers the refurbished Asus AC1200 802.11ac Dual-Band Wireless Router for $26.99 with free shipping. That's tied with our refurb mention from last July as the lowest price we've seen for this router in any condition. (It's also $23 less than you'd pay for a new one today.) It features four 5dBi antennas, four LAN ports, and USB 2.0.

Note: A 30-day Asus warranty applies.
