Also, understand that merely having a flat-screen TV will not give you HDTV...you also need a source of HD programming (over the air or more likely, satellite or cable).
I have cable. If I buy the set will I need to buy some sort of converter? I’ve seen adverts from my cable company hyping their H.D. service or something similar, I’m not that savy and haven’t paid attention to their ads in the past. I’m assuming they would charge a fee for this service.
