Looking for a scaler to work with a Panasonic W4 plasma and a Barco 808 Graphics. Running it with all devices: PS2, Sky, DVD etc. With the recent price drop, what are the main differences between the 3 devices. From what little info that I have understood, the iscans line double only whereas the lumagen vision can scale to any resolution (equivalent to line tripling/quadrupling?). Have I understood correctly and which of these devices are relevant to my set-up? Basically, what I am asking is the Lumagen worth double over the iscan? BTW, my comparisions that I have seen are a line tripled Sony G70 (excellent) to my old Seleco 400 with its internal line doubler (okay to my eyes but very soft on sky pictures). Thanks in advance.
