the DILA chipset is complete SHIT btw. they burn out so fast. their last 3 gen chips have. DLP has also been very unreliable as well as its image no where near the quality of a good LCD projection setup like sony's. Hitachi Ultravision II tv's have an amazing picture quality but are not the most reliable of the bunch.

the best lcd to get is the sony XBR lineup but it only goes up to 40" so far. they just dropped the current series for a new one to be released soon which will be amazing. Sharp has a 65" lcd but its cheapst price so far has been just over 16k.

The entire new sony lineup of LCD and lcd based projections have amazing specs. response times from 2-5ms. release should be end of july.

Plasma's wont last 15-20 years. That is the half life of the brightness. Not true lifetime. Your plasma is probably going to last you around 5-8 years depending on brand. Also the contrast ratio's given on plasma's is also kind of false. Lcd's are rated on a much stricter set of regulations for contrast ratio so you dont see crazy high numbers. plasma's are not so they can say i have a 10k to one ratio.
