Highjinx, Getting a streak-free screen is a crap shoot, from what I've read and even talking to Draper. They did not recommend the M2500 for digital projectors, only CRTS where the streaking is less noticeable. I, however, liked both the price, size and brightness as compared to other screens and was willing to live with the very vague streaks--just in one square foot spot on my screen. Now what's interesting is, I turned the screen around (backside) to see how the image would show on it and wow, it was pristine, evenly lit and about 1.3 in brightness. I suspect the material used is the M1300 material with a coating to get to 2+. Of all the screens I've ever had, though, the Dailite Hi-Power is without doubt the best, but works best with a floor or desk mounted projector because of how the light is reflected back to the source. So for a ceiling mount, it looses brightness. The M2500 was my next choice and has a better color temperature (less yellowish). I have over 640 hours on my current PE8700 bulb and the brightness is still outstanding. I simply tweaked up the brightness and contrast a notch, but it doesn't appear much different than when I first bought it.
