What works best depends a LOT on your experience and tastes. I have a Brillian 65" 720p LCOS rear-projection set and I love it. Brillian was bought by Syntax (of Olevia LCD fame) and is now primarily sold under the Syntax label. You can also get LCOS technology from JVC, which they call D-ILA or HD-ILA. I would recommend going with their PROSUMER sets rather than the regular consumer models.

Regarding extended warranties - a recent article in Southwest Airlines in-plane magazine lambasted extended warranties. EXCEPT in the case of HDTVs and other pricey technology purchases.

If you're going to buy from a website, I'd suggest sticking with known, reputable sites. Brooklyn is famous for its thriving internet rip-off industry (hence the knickname Crooklyn), but they are popping up all over the country. In addition to Amazon, NewEgg, Buy, and other relatively trustworthy sites, you might want to check out TVauthority.com. They know the products they sell very well and will only suggest add-ons when appropriate. They will also discuss your needs via phone or their on-line chat service to help determine the best product and technology for your budget. And no, I don't work there.

Someone was asking about certifications and what not. I'm not a repair technician, but I am ICIA CTS certified, have received training from a few dozen manufacturers, and have designed hundreds of audiovisual systems for businesses and homes.
