I currently have a Sony hs10 which has been well tweaked and looks good. It replaced a Hitachi Ultrablack. After first setup it had the oh-my-god factor and I have been pretty happy for the 3 years I have owned it. Front projection has made leaps and bounds since then and am thinking seriously about it. QUESTION-since the hs10 hss a built in de-interlacer and scaler--I believe--would it be smart to go the dvdo Iscan route so that all video formats are upscaled? The Iscan is obviously better than the interlacer in my Sony and probably better than the FP units as well. For FP--thinking new panasonic PT-ae700u but any better or morelogical choices would be welcome. Ambient light can be controlled completely and screensize--about 96". Budget --under 4000. I love video quality and don't wish to be dissapointed in my choice to go bigger. PS---use it as computer monitor as well.
