As someone who works in the Cable industry I will weigh in here.
A normal cable modem costs about 50-60 dollars (emta's, fancy routers
w/cable modesm cost more). It used to be the case that Motorola CM were
"top of the line" but I think that for the DOCSIS 3.0 modems that has
been passed on to Arris.
So look at the amount they are paying per month, how long they intend to
have the service and if you can get either a Moto or Arris modem at a
reasonable cost and you can crunch the numbers.
The downside of owning a cable modem is if there is a failure. Cable
modems aren't anything special. Like all computer hardware, it will
fail when it's going to fail. If Comcast owns it they will replace it.
If you own it you are on the hook (aside from any warranty).
Until recently I owned a Motorola DOCSIS 2.0 modem and it worked fine on
Comcast's network for about 5 years. It was worth every penny. Other
people owning their own modem may have other experiences.
Some cable companies restrict which modems can be on their network.
Time-Warner has an approved list, and other MSO have a list of
specifically not allowed modems. That being said I wouldn't purchase a
used modem on eBay. What works on one network won't necessarily work on
My business partner has a condo on the coast and has Charter as a
provider. His self-owned Moto modem was resetting every 1-2 minutes and
Charter Customer Care refused to do anything about it (specifically
flash the firmware to something more updated). He brought it home to
Vancouver and hooked it up to Comcast. They flashed it within 10
minutes and he took it back to the beach house. It's worked fine after
