I always laugh at the 'evil projection' comment. Back in '91 my family bought a 50" Hitachi projection TV. It is still our main TV after 11 years, and the total cost of maintenance/repairs in that given time?
$300 bucks.
The only reason I see projection as 'bad' is that it simply will not have as sharp a picture as a tube.
What I would recommend is this: Go to a Best Buy, or a Circuit City, or any place that has a large TV display area. Don't bother with the salespeople...just check out the units. First thing to decide is whether you want a tube or projection TV. Look at the different displays, gauge what you are going to use the TV for, and
choose what is best for you. Once that's done, get a feel for what size TV you want...based on how it will fit in the area of your house, cost, etc. THEN decide the little things, like if you want a widescreen or standard, flat screen or curved, etc. Once you have an idea of the type, then hit the net and search out different models and reviews.
Don't get too caught up in all these new technologies if they are unnecessary.....I mean, if you're just using the TV to watch the History channel and nothing else, why spend 2500 on a widescreen HDTV-ready unit? You can get a really nice tube TV for under 300 bucks to do that.
As for lasting for 25 years.....they REALLY don't make 'em like they used to. And with the way things are going, obsolescence is about 5 years....
