I am about to buy an Infocus SP 4805 and would like some opinions on screens. From the research i've done, I think a white matte screen is best for my lighting situation. I have been looking for an electric screen around 92" diagonal but the prices for most are very high. I am not willing to pay as much or more for a screen as I am for the projector. There are several screens on ebay around the $400 range, but I don't know about the quality. Most of the customers seem satisfied. Also, I am probably going to go with the Sony HT-DDW670 HTIB unless you guys have a better suggestion around $200. Thanks in advance guys.
