I'm considering buying a 50" Samsung HDTV (HLR5067W). Should I also
purchase the service contract they sell with it? (Cost: about $400.)

The salesmen at the stores that sell large-screen TVs all warn me that
replacing the main bulb in this machine costs $400 or so just for the
bulb, and that I'll need to have a service technician do that repair.

What's your recommendation on service policies on such units?
