Thanks Paddy, I'm going to buy screens from GVB, I'm confident they'll be excellent for most of my needs, and I'll try his Lumigrid type as well.
Meanwhile I have a "Super Screen" on it's way for the Graphic, I particularly wanted a Fesnel type screen, I'll see what that's like I can always use the fresnel with one of Geert's screens.
If I didn't already have a Beattie screen on my 10x8, and the excellent screen on my Wista, I'd be interested in a Bosscreen - now in my Bookmarks
