Draper Argent White XH1500E
Could not find any reviews of this at all anywhere on the web... anyone have experience?
Its a 1.5 gain screen with a claimed wide viewing cone. For an inexpensive 150" setup this sounds like it could possibly be the ticket to getting sufficient brightness. Sounds like it might be similar to Da-Lite's Video Spectra 1.5, which is also extremely difficult to find impressions and reviews of (though the little that I did find is not especially favorable). Both are free-hanging non-tensioned materials.
