we dumped comcast last summer for centurylink at $30 a month, and i watch netflix all the time over it. The netflix servers are less reliable than centurylink.
one caveat: the customer service is somewhere in tijuana, based on my experience, and they had 15 minutes of training in how to solve technical problems. they don’t know how to help me set up my non-centurylink email to come in thru my centurylink browser...they use different ports.
but cheap was the criterion, so i save maybe almost $100 a month now and put up with it.
