The cable companies are getting aggressive.
With some of the deals Comcast has lately, with a 2 year price guarantee switching is a no brainer. Only issue with Comcast is their rental fees. By the time you add a Modem rental, with all the $10 fee here and there for extra receivers, the bundle is not as attractive.
At my house I own my own Modem and have a Tivo. Cuts the fees down significantly
You bet the cable guys are getting aggressive. Around here I've had Mediacom come to the door to make a sales pitch. They swear they can save me money over either sat provider and that is probably true though how much is always a question with Mediacom as they don't publish their rates and if you get a rate sheet from them by calling or the sales guy, what it says and what they will offer don't even come close to matching up. Total confusion.
And they charge for the oddest things. I got their 50/5 internet service and pay $5 a month for the modem. The modem is usually installed with their wireless service for 3 months then they charge if you use it. I had it turned off the day they installed, told them I didn't want it and 3 months later a fee for it appeared on the bill. I called they corrected, next bill had the credit and a charge to take it off.
