Depending on the sports you watch there's other good deals deals. 35x12=420$. All access NFL package (for Europeans, not sure about US prices but iirc. it exists and is in the 250$ range) is about 250€/season. I think NBA/NHL are priced similarly. So you could get about two complete pro leagues for the same price (and these are a lot better than normal live, you get all games archived forever, non-commercial versions the day after, Redzone etc.)

If you want college sports or more variety or something outside of the big stuff (winter sports, cycling etc. etc.) then it's meh.
