There is a pretty good article in the December Forum about digital TV 
conversion.  But the one issue that I don't feel is being addressed properly 
is that the current Sap channels as we know them will also disappear in 
favor of the new digital subcarriers of up to five per channel.  The analog 
sets won't carry them, and the converter boxes can't carry any cable 
channels.  So most of us will end up needing a digital ready set anyway.
