Any cons why I shouldn't jump ship at this point?
Ive got both, and I cant think of any reason. I use a Tivo Premier (bought the cheap one and upgraded the internal drive myself, then got lifetime DVR on it). PQ is good, channel selection is good, and the two year price lock in is great if you get the Digital Preferred.
Just remember they will charge you extra (or they do here, not sure about there) for the cablecard/HD. Its $8.50 per cablecard here for HD in addition to the package deal price.
