OK, so to summarize my experience with Prime Support, here is a couple o facts.

The did not attach any list of what has been actually done to my camera, but after I emailed them, I go the list - and I'm impressed! Apart from the obvious things (like replacing the camera body panels), it seems they replaced the lens (probably for my ND filter sticking problem that I had brought to their attention).

But that's not the end - they replaced my (lost) SDI rubber cap, the USB socket that was damaged, and even the grip belt (the latter I have no idea why).

All in all, it looks like they knew what they were doing, and did it remarkably well. Thank you, Sony Prime Support! Both thumbs up (but please, in the future at least close the lens hood barn doors for shipment :))
