From what I figure, 1084 (even the S models) aren't typically owrth that much, problem with them is not that they're bad screens, but they're all so old that they can go bust at any moment. :-| . I'd be very surprised if any of the remaining functional 1084ses remained functional for another decade.
and, oh yeah, 640x400 interlaced???. Nice TVs but sub par resolution for modern monitors (I sure hope that Amiga Ones don't get distributed with a monitor of that low res)
