This ARRIS SURFboard SB6141 DOCSIS 3.0 high-speed cable modem delivers 8-channel downstream data speeds up to 343.1 Mbps for fast Internet connection. The internal filter helps minimize interference for enhanced performance.
Not one of the cheapest options, but this cable modem is one of the newest versions from Motorola (that is compatible with all the main ISPs) and is excellent all around. Used it to replace the Arris rental from Comcast to stop the $7/month rental fee. It boasts very fast speeds that will serve me well in the future should I choose upgrade my internet speed. Setup--including time on the phone with Comcast--was less than 15 minutes. It helped that I was already up and running with a previous cable modem. So all I had to do was swap out modems and call to have it activated. The form factor is smaller than my previous, and it's a standing unit so it takes less desk space. A very minor negative is that the LED lights on the front are super bright.
