Finally! After years of searching (not very intensely I might add) I have accidentally found my arcade screen. The do say you find love if you stop looking for it.
It's a Bang & Olufsen Beovision MX7000 which I am planning to pick-up later tonight. Once received I'll be ordering the much talked about UMSA Ultimate SCART Adapter to avoid all the pain, time wasting and possible component damage of VGA to SCART hacking to get that beautiful arcade quality output we are all chasing.

In the background I have also been acquiring various PC component to use as the guts behind my MAME cab as everything that I was planning to use is now so old it's obsolete or no longer working. I have been 'planning' to do this since 2004 remember. More on the hardware later.
