    I would very much like to hear the pros/cons of a DLP vs CRT front projector.

    Positive for DLP
    A DLP projector will be easier to set up since it will never need anything to be alligned while a CRT projector will need it's CRT's alligned manually every 4 months.
    A DLP projector can't burn in while a CRT projector can. DLP projectors will have a greatly improved image with a digital connection such as DVI while a CRT projector will get little image improvement from a digital connection.

    Negative for DLP
    Even the best HD2 DLP projectors have a contrast ratio of 2,000:1 while CRT projectors can have a contrast ratio of at least 50,000:1. From what I've heard the contrast ratio at which any further improvement of contrast ratio would be unnoticeable is around 20,000:1 which will probably take DLP projectors at least a decade to reach. DLP suffer from a effect known as rainbows since all DLP projectors under $15,000 use only one DLP chip for all three colors. Anyone can see them and they appear as the seperation of the colors red, green, and blue. This is because a spinning color wheel inside the DLP projector is filtering the three colors together. Faster color wheels lessen the noticeabitly of rainbows though this approach will never eliminate it. Rainbows are very dependent on the viewer since some people almost never see them while others will see them immediatley.

    There are many opinions on the strengths and weaknesses of both but almost everyone agree's that CRT projectors are still the best looking while DLP projectors are easier to maintain. I would recommend that no matter which type of projector you get that you make sure it has DVI-HDCP. There is good reason to believe that the future HD-DVD may only output on a DVI-HDCP connection.

    It really depends on what you're looking for. I've owned LCD, CRT and DLP. (In that order)

    The reason why I went with DLP is easy... I spent way too much time fiddling with my CRT instead of sitting back and enjoying a movie. Also, I like to play my Xbox on the big screen so I din't want to worry about burn in. There is also the problem of buying a "used" CRT. Unless you're loaded you're going to have to buy used. If it breaks down it can be a real pain, parts can be expensive and are getting harder to find. (although Curt Palme over at AVS does a good job of keeping people up and running.)
    With DLP you get a warranty (if you buy new) and don't have to worry about it.

    Rainbows. I presently own an LT150 and have never had a problem, nor have my 40+ guests who have come in and out of my home in the past year and a half. Setup is key.
    The black level of my PJ is quite good. Contrast ratios are nice to know but the blacks look great. Remember, I used to own a Marquee 8000 CRT.

    The new NEC HT1000 is supposed to be amazing in just about every way. Much higher CR, DVI, 4x colour wheel, etc... They are getting rave reviews.

    I'm not bashing CRT, it's just not for everyone.

    One last note. I bring my DLP up to a friends cottage once and a while, we watch movies outside and have a blast! Kind of hard to do that with a CRT. [​IMG]
