Jimmybee,
Keep in mind with workflows going data-centric and content being passed around via firewire and other methods one doesn't need an SR deck to reap the rewards of 4:4:4. There are several I/O Boards that will support it, some better than others and many software packages that will do the same. We have many clients working with 4:4:4 with the goal to not buy SRs.
With AJA hardware it's easy to work 4:4:4 and output to 4:2:2 or even downconvert to SD, all on the fly. I would take Mads advice and stick to 4:2:2 but don't put yourself out of the game by not looking at what you can do in 4:4:4. I can say here in the states many of the top companies are requiring "The SR format" for shows and we see 4:4:4 as part of the norm in workflows.
4:4:4 is not an inexpensive venture but not as far out there as you might think. Mads has the rest correct about monitors and scopes, a must for a solid professional production.
Best of luck,
Ramona
