I lost a 4DTV receiver due to a lightening strike without a surge  
protector. I bought a Monster surge protector for ~$80 at Best Buy,  
and it caused a lot of "mosaic" patterns and loss of signal. I called  
Monster and they sent me the $200 model which worked like a champ.

While it is hard to recreate a lightening strike, I am not sure they  
are worthless. But from experience I would avoid the cheap ones.

P.S. Of course, taking the surge protector out of the loop and seeing  
if the Food Network looks better would be a great first step.
