still....Look at the picture at www.avsforum.com
. David Bott tried out 4 high quality screens, before settling on the Draper M2500. Yep, that's an M2500 pictured in the photo of his fancy home theater. He found the M2500 to be the most three dimensional of all of them.
So it's not always a rule of thumb to only stick with 1.3 gain screens. 1.3 gain can be better if you have the light output necessary but not everybody does (without driving the projector to the point of blooming). Not everyone wants to go for a smaller screen size or sit closer to the screen. Not everyone have walls painted black (an M2500 has better ambient light rejection, including scattered light from the screen). I have personally visited his home theater as well. The picture was great!
If you have money, try both. As long as the projector is cieling mounted, more than 50% of the time, you'll go for the M2500, unless you really focus carefully on all other nuances and aspects of the home theater (size, viewing distance, etc) - then it's probably a 50-50 break even.
Just make sure the projector is cieling mounted, you're sitting in center, and you're sitting at least 1.5 screen widths away from the M2500. Otherwise, you won't get the best effect out of a M2500. This is good if you can normally sit in the prime seating position all the time.
Most of the dissatisfaction reports comes from people who cannot sit in center, or the projector is floor mounted, etc.
