Absolutely. Do your research. I have had two DLP's and they both failed me right at about 2 years. DLP is for the birds in that regard although they provide a pretty good picture for the dollar! Do not look at all of the reviews on amazon or other sites as these are typically customers that have had the sets for a few weeks or a few months and of course they love them. They just spent $1-2,000 on the set. No one is going to hate it. Research using the brand or model specific threads at AVS and look a couple of years into the thread to find out what really goes on. The threads always start out with, "WOW, where do I get one of those!" and they have a tendency to finish with "Where do I get this fixed? Is anyone else having this problem too?" LOL
At any rate, nothing is trouble free and I would suggest an extended warranty, but read the fine print! While some things are not covered, many of the repairs can easily reach $500 to $1,000. Good Luck.
