Please. Tell me why I shouldn't switch to Comcast. Please.
Well, I hate to say it, but perhaps you should. If all we are able to deliver is 3.0Mbps DSL, and if that speed is inadequate for your needs, I just don't have a good solution.
That being said, stay as long as you can stand to - and if/when you do leave, do retain your services aside from access here; email, website, domains, backup dialup, etc. Our staff can assist with this.
