EverythingDeals via Amazon offers the Arris SBG6400 SURFboard DOCSIS 3.0 Cable Modem and N300 Wireless WiFi Router for $54.99 with free shipping. That's $45 off and the best price we could find, outside of the mention below. (We often list similar modems without routers for around this price and in the past have seen refurb combos like this for the same price.)

The modem features eight download channels and four upload channels capable of up to 343MB/s and 131 upload speeds. The router features two Gigabit Ethernet ports and USB.
