Since Cox is my only choice, I wouldn't know to be able to compare. I pay $100 month for HD Digital cable(no premium channels), and basic internet. I didn't choose to have a phone because I just use my cell phone, but it would only cost me a few dollars more for digital land-line phone with the package I have.
It all depends on the cable TV packaging too.
You see offers like Cable TV, Internet and Digital phone for $100, but that is just for basic cable, then when you add your DVR players, extended stations, premium stations, HDTV, faster internet, etc, etc then add all the other taxes and fees, you could be spending $200/mo
So it all depends what else the person wants in the whole package.
