Here is my situation:
I need to purchase a HDTV that is at least 55" or over for a family room that is 20'x22'. Our viewing distance will be about 18-20 feet away, and will (for the most part) be a direct-on view. The ambient light will come from two picture windows located off to the left of the tv. Of course curtains can be drawn to help control the light. The set needs to handle a variety of sources.....upconverted DVD, xbox 360, and SD and HDTV from Directv. This tv will get allot of use, so it needs to be sturdy.

I was looking at three different models:
Sony 55" or 60" SXRD A2020 models
Toshiba 65" 65HM167
Mits 65" 65733

Which of the three, if any, would you go with? Why?

Thanks for your thoughts and opinions!

There is no correct answer to your question. The Sony LCOS and the Tosh and Mits (and Samsung) DLPs would all be great given your situation (one is not better than another).
