Have you considered Monkeybrains? For the price the service is fantastic, and with some of their new upgrades speeds are pretty good for most of SF.
Caveat: I work from home so I keep my comcast subscription as a backup and have a router with automatic failover. I would say this is not worth it for most people and just Monkeybrains is sufficent.
