3-4k for projector? You should be able to get a good midline for 1500-2K. Also 2k for the screen? DYI for much less($500?) with reflective paints and such freeing up the savings for the A1400;\)

Honestly, I have no idea as to projectors and screens. I just think we need another person to review the A1400.
