Called Time Warner and explaind the DSL-Dish combo offer. They countered with a $20 credit for each of the next 12 months. The downside was that it took 22 minutes and 3 different people to reach that point. Hey: I knew this wouldn't be easy...gotta stay calm... I did not argue for more credits - by the time I got to somebody who could help me I just wanted off the phone. I'm happy with the $240. I figure they know I don't really want to go back to Ma Bell, so I don't think they were going to up the ante much beyond that number.

This pretty much locks me into the cable-VoIP mode for at least the next year. Next up is picking a VoIP provider...
