I too have been looking for the DLP of choice. I too noticed the "halo" effect on a recent trip to a local Home Theater store. I'm not sure which models I was looking at specifically, but it sounds maybe one of the other models may handle that better. I've been leaning to the Samsung until recently, as I like the ability to have the HDTV tuner onboard, though I'm not certain if you still have to have anything extra for satelite or cable.
The other thing I heard from a co-worker was that when Mitsi came out, they were building great equipment. About a year ago he bought a rear projection big screen and has nothing but trouble out of it. The repair guys that have made many trips to his house, finally told him that they have more calls, problems, and repairs out of Mitsi TV's than any other. His recomendation was Sony, as they have the fewest calls on those.
Like everyone else, the feedback that is posted, the better!
I would like to see if anyone else has had issues as my co-worker.
Thanks!
