Not sure why anyone would hate on DLP just to hate on them, but some of that hate might be from past problems (Example: Rainbows) with Rear Projection TVs. Shoot, I was guilty of this with Plasma while shopping for a new HDTV recently. I held burn in issue against new Plasmas, but have learned that's not such an issue these days. Sorta like some people still believe new DLP/RPTV have the same problems as past Rear projection TVs.
So far we love our 73740 Mitsubishi, and its picture is amazing. We never have been so immersed while watch TV like this before, that's for sure. We still can't believe the price we paid for this TV experience. My Wife had to go to the Hospital the other night, and the 4 Paramedics couldn't stop saying how great the TV looked. They where seriously taken a back by it, and Family/Friends have been the same way. When I told them we paid ($1,644) for the TV their jaws hit the floor. One guy said he thought we'd paid $4,000 - $6,000 dollars for it, and couldn't believe it only cost that much.
Some people are going to want a thin TV because that makes them happy or it works for their Home decor. Some of those LEDs TV have a great picture, but I couldn't live with with the Flashlighing & Clouding issues some (Edge-lit ones) have. It was a roll of the dice pretty much, and it knock them out of the running for our next TV purchase. It was down to 3D DLP or 3D Plasma, and the 73740 DLP won out in the end. No TV tech is perfect, but my advice is just find a TV that makes you happy. This 73740 DLP works for us, and we are so pleased with its picture. HD stuff really shines on this TV, and watching 3D/2D Movies is just breathtaking.
