Picked up NBA TV last summer specifically to watch last year's summer league games. For $5 a month I get NBA TV and couple other (non-basketball and never watched) channels.

I don't have time to watch other games so I didn't even use the NBA TV channel too much last year. I often caught the NBA Recap show in the morning which was useful. Otherwise, there's a lot of a advertising and classic games in addition to NBA and WNBA games in season.

I plan to cancel after this month's summer league action.
