ITT: people who made the mistake of buying expensive electronics from best buy
Honestly, don't do it. It's a shitty retail store. You're introducing a middle man in an industry that seriously doesn't need one. Not to mention that Best Buy prices are usually higher than they should be...
Buy direct from the manufacturer if at all possible, and get your service plans with them. They clearly know more about their own products, and should you need to get something replaced, have more knowledgeable techs. Don't deal with the 17 year olds at Best Buy. I think it's smarter to buy online at Newegg or TigerDirect at this point, because most sites offer service plans from the manufacturer and not their own. If you feel uncomfortable buying something you haven't seen, go to best buy, look at the TVs, pick one you like, go home and buy it online.
