There was a recent thread about DCXpert that deviated somewhat and there was some disussion about DCXpert and it's "relationship" with CRK here:

In one post I mentioned that I had a potential warranty issue with my K3iii that I bought through DCXpert, so I contacted them about how to proceed. I was asked to contact CRK directly. I phoned the Melbourne office and spoke to Rob and he said to take the camera (and a copy of my invoice - on CRK letterhead but charged to DCXpert) to the Perth office of CRK. I took it in and they sent the camera off to Melbourne for an inspection and repair (if that's what was needed).
I've just had a phone call and my camera is ready to collect. They tested it and couldn't find anything wrong but have told me to take it back if I have any more issues. There was no charge in spite of nothing being wrong - the whole process took one week. Once again I'm very impressed with CRK's service - they did a great job on a lens for me a couple of years ago.
I guess what I'm trying to say is that Aussies can confidently buy gear through the DCXpert website with the knowledge that the gear on their site is not "grey" and if there are any warranty issues then CRK will handle them professionally and without quibbling.
