Bex,
I don't want to make the SONY sound any better, because it probably isn't. However, my good lady wife has just had her non-flickering, LCD TFT display replaced at her place of employment, due to the headaches it caused her. She's gone back to her trusty old CRT. Makes you wonder what those BARCOs might do to the old grey-cells if they aren't tested properly. And if the gods have any evidence that replacing the SONYs won't avoid any headaches or eye problems, can you really see them spending the MILLIONS that would be needed to re-kit both ops rooms with BARCO or similar. They won't even buy us pens anymore...
PS Don't rely on Scott's countrymen for tests that suit our tender little European sensibilities. You wouldn't want to know what they allow their beef cattle to be injected with..
