This decision has become really tough for me. I was originally going to get the 4805, but due to it not being true HD I passed on it and worked my way toward the Sony HS20. Now that TV authority is having a package special where you get the 4805 and a 106" screen for cheaper than most sell the 4805 by itself I am tempted again. The main drawback (the only one that I know of) is the lack of true High Definition. Is there any negatives to this projector? I figure if I did get a HD projector I would have to buy the HD receiver, HD dish and satelite receiver, and then the HD programming. It kind of seems like it is not worth it just for a couple high def channels. Anyone have any feeling on this projector and not having a high def projector?
