i had this problem last basketball season, so i paid the money and bought a sling box, changed my life. no subscription, just 160 for the box, then 30 for the app. i use it everyday.
Love my Slingbox. Don't know what models are available now, but I'd stay away from the Solo. Caps shot their wad after about 1.5-2 yrs...still need to get the board fixed...hate not having it going! I've read it's a pretty common problem.
Edit: Just looked at their site. Just the Solo or HD models, and the Solo is half the price. Guess it's worth it, just make sure it stays in a well ventilated area. Cheaper to have caps replaced than paying double the price for the box to begin with
