I hear you Asi.
I'm just keen (for now) to try some imaging with the same camera you, DP, Mike etc have been using so I can judge for myself the comparative performance with the NexImage which I've used for the last 5 to 6 months.
The other good thing is there's plenty of advice out there on the 840k ... coz that's what most folk have been using.
I can always sell the Pro II to upgrade later, after all you blokes have figured the 900nc out
