I have a DLP, and I strongly advocated DLP, for screen sizes larger than 36", back in 2006, when we bought ours, and even 2007. However, since then, LCD and plasma have come down in price by a substantial amount, and at this point I think DLP has had its day. The only thing DLP has going for it over plasma (at least) is power consumption -- indeed, most plasma televisions currently on the market would be banned from sale in California under a new state law there. However, LCD, while incurring greater power consumption then DLP on average, is a decent compromise, and the vast majority of (though not all) LCD HDTVs would comply with the new California state law.
You still get more television for your dollar with DLP, but that advantage is much less than it has been in the past, and the space and weight advantages of LCD over DLP are significant.
