But personally I think that the dlp has a much better picture than the lcd.
I am currently in the market for a 60" rear projection TV and have been looking at the Mit 62725 DLP as well as the SONY 60XS. I am torn between them PQ wise. Not sure which one to go with. Anyone have any advise on the two types...LCD rear vs. DLP rear and these two tv's?
