I wish this kind of sanity prevailed in all online forums, particularly on the subject of lighting.

Incidentially, I did go for the 2 x 650 and 1 x 300 deal in the end, with quite a few extras thrown in for free and of course with a view to expanding my lighting kit further in the near future.

My lights should be delivered later in the week and thus far the seller has been an absolute pleasure to deal with on a personal basis and in terms of price. I suspect I'll be posting a recommendation for UK Arri buyers on this thread once they arrive.
