AV-Sales in Kent, Tunbridge Wells, may have the Fuji screen set up, PM Alistair Collie and ask him. They have it at £4.5k at the moment though, so ask him his best price and have a hunt round to see what they are going for, they seem to be up and down all the time.
Media Box is a box that has all the inputs and TV tuner in and sends it all to the screen with one cable.
Video processor and scaler is the same thing, they deinterlace and scale but they do so much more than that so people are starting to called them by their proper name now, Video Processors.
This really does the same thing but usually no TV tuner in it, just very high quality processing. You can sen the screen the exact resolution that your screen needs and therefore bypass the cheap processing that is built into the screen to get a far superior picture.
However the reason everyone loves the Fuji is it uses its AVM processing which is very, very good, because of this if you are going to use an external scaler I would consider the Panasonic 50PHD8, the Fuji uses Panasonic glass but the in built processing is not as good, but if you are going to use external processing it doesn't matter.
I actully prefer the Panasonic to the Fuji when using an external processor, and when I bought mine I could have got the Fuji for £40 less, but the PHD range is the most CRT like screen out there. The Fuji is a little brighter than the Panny but at the same time it has this slight digital feel to it, better than any of the other plasmas out there but the Panny still wins for me.
If you want to see a Panny set up and can be bothered to come up the M11 into Norfolk I am about 1h45mins away from you and you are more than Welcome to see my set up.
