Things to consider.
You can get 46" DLPs if the screen size is a major concern.
The DLPS will display all 1280 pixels per row in a 1280x720 720 Broadcast wheras as many 42" plasma only eliminate 20% of the pixels in each row since they only display 1024 pixels per row using rectangular shaped pixels in order to save manufacturing cost.
Bulps are more like every 2-4 years and cost $200.
If you really want great PQ then a 47" 1080p LCD Flat Panel would be great at your viewing distance.
