Bit of a different experience here: Cox Cable recently performed the same upgrade, but instead of charging me $250 for an installation, they instead decided to inject JS and HTML into every non-https site I visited (wel, once every hour or so) with a reminder that I've been upgraded to a new tier at no additional cost, but I need to buy a DOCSIS3.0 router.

I... I think that's a fair deal better than being charged $250.
