DLP, LCD, XVGA projectors, what are they and

how good are they? I have seen several TV sets with the mentioned technologies. XVGA ones are directly related to computer monitor applications, but why does it seem to me that these rather compact projectors can also be used for home theater settings? Can someone give me a run down of a product that is from each one of these technologies, that is reliable and can be used for home settings? What would happen if you would use a XVGA or SVGA projector at home? Any specific recommendations would be appreciated, especially under 2K.

PS: The choice of purchasing a DLP set goes as high as about $4000 for a Samsung model but the DLP projectors see, to run about 2K, durability is the issue?
What about bulb cost and bulb life?
One drink's too much, and 20 aren't enough. It would be a missive to answer your questions. You might try looking at the FAQ's at more video-oriented sites. Feel free to email me for some suggestions.
