$62.95 + $3.00 modem rental would be the cost to me in the Seattle area for Ultra, but I also have a TV service. From what I understand, they are telling you they will switch you to Ultra for $61.95/mo. (probably there will be $3/mo. for modem lease as well) and you have no other Comcast service.
Interesting and I have no idea why.
If you do get a D3 modem and the D3 service, let us know how it goes and what you end up paying in this thread ---> »
