Linksys Official Store via eBay offers its refurbished Linksys AC1900 Version 2 802.11ac Dual-Band Wireless Smart Gigabit Router for $54.99 with free shipping. That's $50 off and the lowest price we could find. (For further comparison, we saw a refurb Version 1 router for the same price three weeks ago.) It features simultaneous 2.4GHz and 5GHz bands, data transfer speeds up to 1.9Gb/s, a 1.3GHz dual-core processor, beamforming technology, four Gigabit Ethernet ports, USB 3.0, and four external antennas.
