I am looking at this screen as well, thanks for your info on it.
I am wondering though, according to the eBay listing it is a 1.0 gain screen, would it be bright enough for 3D? I have an Acer H5360 which is still pretty bright at 100". At night my room is very dark but my white ceiling causes the screen to wash out slightly, so this HC Grey would help with that, I am just worried it would be to dark to enjoy 3D using DLP-Link glasses when I go 3D in the future. Anyone know if the H5360 could use this screen for 3D?
