we are putting in a home theatre, in our basement....?

measuments aside, what are some opinions about hometheatres with tv's, or projectors....do projectors have good picture quality?

Being that this theater is going in a basement, I would suggest going with a DLP front projector. DLP currently offers the best possible picture for the least amount of money. A ceiling mounted projector in a basement with a drop ceiling makes the wires easy to hide and the fact that it's in a basement makes unwanted light almost a non-issue. DLP front projectors have every bit of the picture quality of flat panels without the worry of burn-in and the inevitable picture fade of plasma. The contrast ratio of DLP is far superior to either plasma or LCD and if you're worried about replacing a bulb in four or five years, remember that a flat panel LCD TV also is back-lit so you will be replacing a bulb in that TV as well...

If a front projector is out of the question, my second choice would be a DLP rear projection TV. These TVs use the same bulbs as LCD and front projectors and the viewing angle problems that these are known for have been greatly reduced. These are also the least expensive large-screen HD TVs available right now so if money IS an issue (as it is with most of us) this is where you want to go. Don't let the price fool you; these TVs are very durable and have a superior picture to both plasma and LCD.

A few problems I have with plasma: Despite what some may say, the gas inside the TV will eventually become inert, making the TV useless - it cannot be filled back up. While it may last 40,000 hours, the fact of the matter is that the gas has a half-life, which means the gas starts becoming inert the moment that the TV is manufactured. The picture will progressively become darker and darker until you have to turn the brightness up so high that all of the blacks are washed out, which leads to the other problem with plasma: It doesn't have very good contrast. The best you can ever get with a plasma is a dark gray.
