If you upgraded to HDTV over the holidays, you should consider dumping cable for totally free broadcast HD. AntennaWeb will show you which antennas pick up the most channels at your address.
The site's totally free, and all you have to do is punch in your address and whether or not you've got tall buildings or giant plants nearby. It'll then give you a list of stations, how far they're broadcasting from your place, what kind of antenna will pick up the best reception for each one, and even where to point your antenna. It's free (along with the channels), so definitely give it a whirl and consider kicking your cable company in ass, like I'd very much like to do to mine right now. [Antenna Web via Lifehacker]
