Modem equivlent to Arris WBM760A

I am currently renting a modem from Comcast. I will likely continue using their service and at my current rate so I think that long term it would be better to buy a modem. However when I upgraded to my past plan they said I needed a different modem. The modem is a Arris WBM760A. If necessary I will by the same thing, but I was just wondering what kinds are equivalent to this kind so that I can price compare. I don’t know much about cable modems so I’m not sure where to even start comparing.

Here is a link to the modems specs on AmazonArris.

It’s just a standard DOCSIS 3.0 modem, so any cable modem would work. A good replacement would be a Motorola SB6121. You could also get what’s called a ‘modem gateway’ which has a built-in router and WiFi access point.
