Wow! I am not looking to even spend that much on a TV. I am guessing that you are referring to a video processor? There was a post earlier recommending something similar from DVDO. It is supposed to work great, but the cheapest unit is (I think) $1,499.00 in US$.
I would not think twice about spending one, two, three, and maybe up to five hundred dollars for REAL nice video. But $3,500.00 US? Too rich for my blood.
