Update:
So it looks like this might be adequate for my needs, and I won't be buying a TV any time soon. Thanks all.
- I found digital channels for local broadcasts, ie. 107 = 7, 105 = 5, etc., and EyeTV automatically gave me the bigger, sharper picture...quite nice.
- The channel guide isn't terribly accurate, so it looks like some hunting will be necessary.
