I bought the Da-Lite fabric cut to size from an online dealer in Canada, if you call Da-lite they have a list of dealers that sell fabric. If you go with the Z5 i would suggest the Da-matte white (1.0 gain), the cinemavision (1.3 gain) which i have is pretty bright in a dark room and is not required for your setup, if I did it again thats what I would get, the matte white gives the most accurate PQ. The Z5 is alot brighter than most folks think, at least in a small to medium size room, my unit is ISF calibrated and is on econo mode.
