Check out tvfool.com as well. They give a more complete report than antennaweb.org, and they have a forum that you can post in to get advice on antennas. Although, they don't like to recommend indoor antennas too much.
Are your channels uhf, vhf, or both?
If they're uhf, you might check out the new Clearstream antennas by Antennas Direct. They seem very cool. They won't pick up vhf though ... you need old rabbit ears for vhf...
