OK, thanks...I guess that all that I need is ATSC if want OTA channels. After searching the web and a visit to Micro Center there do not seem to be any quality, reasonably priced options, so I am probably going to just bite the bullet and buy a new, small HDTV.
If anyone is interested, I found this unit at Micro Center for $100, but when you read the reviews it hardly seems worth the $60 (plus S/H) from Newegg.
