As one of its daily deals, Woot via Amazon offers the factory-refurbished Motorola SurfBoard DOCSIS 3.0 Broadband Cable Modem, model no. SB6121, for $44.99 with free shipping. That's tied with our mention of a refurb from January as the lowest total price we've seen. (It's also $25 under the best price we could find for a new unit today.) It features support for IPv4 and IPv6 and enhanced network management. A 90-day Motorola warranty applies. Deal ends today.
