I'm looking for a 9ft-10ft wide 16:9 Screen for my Barco BG801S. Although I'm happy with the image quality at this size I intend to change the PJ for an 808 or 1208 as soon as fund allow. What specifications/properties/gain would you recommend in a screen for these projectors? Also..Bearing in mind funds are limited right now what could I expect to pay for :- 1/ An electric model 2/ A Manual Pull down 3/ A Fixed Screen Are there any inherent problems buying screens second hand? Many thanks, Mark.
