There grey, i have refereed to them and others as Box Shifters, there are many of them globally and widely used by many leading manufacturers, they fully import with 12 months full warranty, offer repairs and service, they ship to your door FedEx, DHL etc, often they may have depending on the scale of their business volume and a product range in stock of fast moving items in a small warehouse here in Sydney like you find in Brooklyn, i went to B and H for a 50mm Nikon lens, they were on back order, i went to a box shifter in a unassuming warehouse in Brooklyn who had genuine stock at a great price, while there i incessantly or naively asked, are you part of B and H they said oh no, We are a wholesale importer and distributor, i guess you could call us Grey Market.
They had all sorts of stuff staked to the ceiling.
Many of the shops selling camera gear in Manhattan on the tourist strips got a lot of their gear from them so they said.
You can by appointment in Sydney call by and collect a popular product if held in stock but not with all Grey operators.
Who is safe good or bad is based on experience of friends and people you know well, there are far more good ones than bad or fake.
Many of my friends bought their D4 D4s d5 and lenses from Gray dealers, absolutely its not for everyone, many of my Asian friends have sorted out the good ones people seem to align with and when they do the delivery and service is lightening fast in their experience.
These kind of dealers import places have been around for decades, many of our club members buy gray and never had an issue...........as long as you join up for free as a member and have an account, there really good, usually if a product is faulty they ship it express to Hong Kong or Japan and send you a replacement subject to what issue is, or they may repair it.
I wanted a 200 F4 Macro Nikon, the local Nikon dealer had placed the order, it would be 7-10 days before shipping with a 2 -3 day delivery, i cancelled the order, bought on line from a Grey dealer in Oz called Digi Direct at the time, i paid on Thursday night around 11 pm with Pay Pal, Sunday yes dam Sunday 10 am there is a knock on my door it was my brand new Nikon lens shipped from Hong Kong, many of my friends mostly from Asia have all had withe the right grey dealer noting but a great experience them sleeves of super fast delivery with never a product or service issue.
Now the caveat: I have no experience with CCC i also have not heard any complaints either, Its up to the individual to choose where and what they buy and from whom, i make zero zilch recommendations, yes there are poor or suspect operations and services on line and that applies in many fields.
Generally I have found with Grey dealers, if there are a group of people i know or close friends who have worked out the good dealers i as so many have had NO issues with delivery or service, they are super fast with both.
What led to this point was the price of the Z9 has come down, be it Grey dealers doesn't matter, its being condoned.
