I am getting a new projector ,a Sony VPL- HW50ES with a new Stewart Fierhawk G3, 100" diag. I no longer have a use for my Stewart UltraMatt 150, 82" diag. that I used With a Dwin HD700. The old screen is a 1.78 aspect ratio and has the Luxus Deluxe frame, and is in good condition. What do you guys think would be a good asking price for a used sceen at a consinment A/V specialty store? Or on Ebay?
