Nathan (nfordenfield) popper over last night to work out where my BG801S will have to sit on the floor in order to run under floor trunking to the correct spot. I don't have a screen yet, but a dust sheet over the window at 8ft produced a wonderful image, even without blinds on the windows. Out of curiosity we pulled it back to 10ft, this would be a good size as it will cover the window's width completely. The picture was more than acceptable, it was very good. Not as clear close up, but at the 20ft viewing distance it was great. This is with a dust sheet too. Nathan used a laptop with the equivelent of a line-tripled image. I don't have a scaler yet and will look out for a quadscan-pro second-hand. We also think there is a way to use a 10ft pull down screen in front of the window. Mark.
