I have been using the 20-year antenna, brought from Radio Shack for $3. You can buy similar stuff at dollar store. I started using it for HDTV over 4 years ago, and it works perfect. The special HD attenna does not work for me because of its directional selectivity. Our TV stations are not located in the same direction, so we can only get certain channels but not all with the fancy HD attenna. In most cases, the cheapest attenna works just fine. The best one is outdoor attenna.
