Glad I read yours before plunking down my pennies.
Tell me, how do you find out who the real supplier is? Scanning again the product description to find out. I have found one mistake so far: it claims this product was first available in October 2001. Which it was not. I'd better be sure the main parts are all included. I'd hate for the savings to be because they left out something essential. But did you see how many happy electronics purchasers are on this thread? I was very close to just buying, but I don't need the hassles of a grey market purchase.
I still can't find any hint of the supplier. It does not appear that anything essential is missing from the package, though.
Well, if you take a look at the availability, it should tell you. For instance, if you go to the Amazon web page and do a search for hasselblad h3d, you'll see the availability near the top that it's sold by, and ships from Adorama, and it could be yours for just $34,000 dollars. No, that's NOT a typo. You pay a lot for a 39 megapixel camera, especially one by Hasselblad. Oh, and I believe that's for JUST THE BODY: No lens. Figure on adding several thousand dollars for a lens.
On the other hand, if you search for a Nikon D300, you'll see that according to the availability, it ships from and is sold by Amazon. Oh, and the fact that Amazon offers a factory mail in rebate means that they are an authorized Nikon dealer, and Nikon will honor the factory warranty.
You might also check with the manufacturer to see if Amazon is an authorized dealer. BTW, if you're looking for video, two reputable mail order dealers are B&H and Adorama. If nothing else, they can give you prices to compare.
From many posts here, Amazon seems to be highly regarded and reputable. While I've never bought any electronics from them, I do know that in the 2 times that I bought DVDs that came in defective (out of countless CDs and DVDs that I've bought from them), Amazon didn't hesitate in giving me postage paid mailing labels to ship them back, and Amazon cross-shipped replacements.
