Has anyone had the chance to compare the 5000 to the 4805? I'm wondering if it's worth the 500 bucks difference? Also, I'm probably only going to be sitting 9 feet away from the screen, with 86-100 inch screen, so will I see the scan lines? I've seen some other projectors at this price range, like the epson and some others( i can't remember the brands) and the lines were terrible! Is infocus really THAT much better at the same price range?
