Thanks to all three for the suggestions. The GH4 sounds very nice, but strange to my view, as a camera first. However it seems to have a lot going for it and as Chris suggests wait for the GH5. Love discounts etc. The lack of xlr's is still a difficulty. The z150 sounds like a great replacement but a bit pricier than I want. Maybe the Z70 is a better mix. I will have to check it out.
Thanks again to all three of you.
