Walmart offers the refurbished Motorola ARRIS SB6121 SURFboard DOCSIS 3.0 Cable Modem for $44.78 shipped. That’s just over $55 off the original MSRP, $25 better than Amazon’s current new condition listing, a touch lower than our previous mention and the best current price we can find.

This is the best-selling cable modem over at Amazon where it is rated 4.5/5 stars by nearly 9,000 customers. It features DOCSIS 3.0 capabilities to ensure some of the fastest speeds available to consumers and can hit up to 172Mbps down and 131Mbps up. It is compatible with Comcast, Cox, Charter, Time Warner, Mediacom and Brighthouse services, although we recommend confirming with your service provider first.

Motorola’s SB6121 is my cable modem of choice: I’ve owned this model for about a year and have found it to be a reliable product. Aside from saving money on the actual modem purchase itself, this deal also brings monthly savings in the form of avoiding rental fees from your ISP. I save $11 a month by owning my own modem instead of using one from my provider. This modem will pay for itself in less than six months in most cases.

A 90-day warranty is included.
