Amazon offers the Arris Surfboard DOCSIS 3.1 Cable Modem for $189. Clip the $30 off coupon on the product page to cut that to $159. (You'll see this price at final checkout.) With free shipping, that's tied with our May mention and the lowest price we could find now by $30. It features 32 download channels, eight upload channels, and two Gigabit Ethernet ports.

Note: It's approved for use with Comcast Xfinity and Cox Cable and pending approval from Spectrum. It's not compatible with Verizon, AT&T, or CenturyLink or with bundled voice services.
