Let's keep this metaphor going:
The way Dish sees it, the 211's tuner is only there to compensate for their lack of satellite bandwidth; it allows you to get HD broadcasts that they simply cannot or have not yet provided. More like the streaming music player on a phone, compensating for a lack of onboard MP3 storage on said phone. This is a feature which will not function if the phone isn't active. It's a value-add feature that compliments their service, not a matter of life and death.
Reinforcing their POV, if you don't subscribe to local service as a Dish customer, the OTA tuners on ALL of their boxes are incapable of downloading OTA guide data. The guide info is downloaded via satellite, making a dish-less box almost entirely useless. You can't even access My Recordings on a DVR without first pinging the satellite to verify service.
mruk69 makes the best suggestion. Looks like you may be able to get $40-60 for it at auction, which will just cover the cost of a good OTA box. Unless you have a government coupon, in which case you'll definitely get a good OTA box for $100.
