Blackvue.com currently have stock in.
They're also running a special offer for a free CM100LTE module for Cloud access (normally 178.99 dollars, 3 models available; US, Global or Japan).
I'm in UK and have ordered from there.
Blackvue DR970X Plus 2CH with 64GB SD card & CM100LTE Module for 474.99 USD. (£348.09).
Import charges for me were managed by DHL, the courier and cost £78.78 for the UK which gave a total cost of £426.87.
It was despatched from South Korea, and took 5 days for free standard delivery, so don't recommend the express delivery in case you need it urgently.
That is very cheap considering it's the latest 970X Plus 2CH plus an LTE module.
Buying those in the UK would have been £549 + £169 = £718
Here is the link to the offer;
