I'd add nothing except to say that I'm not certain the extra cost of an FSii, over the mark i, is worth it. You get an extra PP, RAW out and FHD120 continuous, if memory serves.
Unfortunately the extra PP probably isn't one that you'd use unless you need a really quick turnaround, the RAW from this particular cam isn't all that great and the FHD120 is kinda soft too.
Same as @kye I'm mainly a hobbyist (although watch this space!) but if I was earning my living shooting video I would go FS7 without a second thought, given the kind of budget you're looking to put in. I think it will be a long while before that camera isn't a money-earner - and if a client wants something that it can't provide there's always rental.
