I would like some advice form the community on the following idea before I go forward. Since the analog to digital switch a few months back one of my spare TVs only gets a few basic channels, I detest the cable boxes and DTAs from Comcast, so I was wondering if a Series 2 or 3 (with no subscription) would do the trick. I am contemplating picking up a used Series 2 or 3 (from eBay or Craigslist) and using it in place of a Comcast digital adapter. I am hesitant to get a service subscription for it because I rarely use that TV, I just need it to allow me to receive the additional digital channels, the guide menu is not a huge concerns. Thoughts, ideas, suggestions are all welcomed.
