If you shop around you should be able to get an igloo box for around $89. I signed up to a 12 month plan and get the channels for $10 a month. Basically it gives something for the Missus and kids to watch. Other than PPV and channels, its only feature is live pause.
Can you reliably find a site to stream the sport you want? If so, I'd flag the Igloo, spend at most $80 on a chromecast instead, coupled with Plex for serving movies, music etc.
