I have been using a Net Return and TV for my simulator set up for 8 years now. My space is limited, however, I'm seriously considering buying a screen for my Net Return and I was considering an Optoma ZH400ST projector. Due to the limitations of my set up I only have 7'-4" of space between the screen and the back of the projector. The image size would 8'-0 wide by 6'-0 high. I can control the lighting as it's in a garage with no windows. Does anyone have any experience with this projector? Also I would be interested to hear if anyone thinks the image size makes it a waste of time and money.
