Yesterday, a person at my local CC (circuit city) was buying a 50" Sony LCoS. The sales person was saying that the lamp replacement will cost $500, and this was the reason to purchase the extended warranty. I don't know about Sony's lamps being so expensive, but lots of people here has said that, say, the Samsung DLP lamp for the 42" costs around $200 or so. So was the CC sales rep bulling the customer to make a pitch for the extended warranty? What do you think? I'd appreciate any comments here, for I am planning to buy either a DLP or an LCD (which hopefully does not require lamp replacement). Btw, the same sales person was quoting that such a lamp would last only a year. I usually think it would last longer, perhaps two years. I do doubt that these lamps last more than 2 years. So again, I'd appreciate any comment. Thanks.
