If you're a scammer, I really don't care how you feel.
If you're legit, then you should acknowledge why people are suspicious of you, and what YOU need to do to attract legitimate buyers, instead of condemning people who have valid concerns as "paranoid".
You have no idea who I am and I have no idea who you are. It's not personal. But, when you raise so many warning flags, you might want to give some serious thought to how you can establish your bona fides to prospective buyers. There are reasons why people look for a extended and positive hisotry on ebay. There are reasons why PayPal got sued for failing to adequately protect some customers.
So face up to the fact that there are too many successful scammers on the internet, and, if you're truly not one of them, think of how you can effectively distinguish yourself from them.
So far, nothing that you've done is particularly effective in proving that you actually own, and intend to sell, a very expensive D2X and lenses. Anyone can "quote" serial numbers and make excuses for the unusual background story you've laid out. And, short of an in person showing of the camera and sale, or an escrow arrangement, don't be surprised if you lose a significant percentage of propsective purchasers, while you're busy being angry at "paranoid" people who have every reason to be wary of you.
Like I said, it's not personal. Don't expect people to easily fork over 5 to 10 thousand USD. I susupect that the average potential purchasers of photographic equipment that costly and sophisticated are also likely to be sophisticated when it comes to buying from strangers.
Oh, and if you are legitimate, while you're too busy being angry at and ignoring the need for safeguards, you might just end up getting scammed yourself.
Be careful and don't blame others for being careful.
