I kept Comcast when they bought out Warner in our area years ago. Have paid $40.12 a month for cable internet ever since that time. Also dropped AT&T for business land line and went with Vonage for $10.00 a month two years ago. Vonage also includes efax number with no additional cost. Most of our calls are long distance so saves us lots of money and works well thus far.
Comcast Xfiniti is far superior to DSL, paying $20 a month for 25 mbs only, using Directv and Vonage. No reason for a ground line any more unless you have zero options.
