Just wanted to mention here my experience with Bob.
I bought six years ago Nikon 300/2.8 AFS II lens from him, I trusted him and wired money all the way from The Netherlands where I am located. He sent me the lens in better than his described condition from US where he is located.
After that I have purchased many times many expensive items like Nikon 600/4 AFS II, 70-200/2.8 VR high value item, I did not even ask for a single picture of the items, I just relied on the description he gave on the item.
He is a rich hobby photographer, he keeps on buying new stuff, playing/experimenting with them, and selling them. I totally vouch for his honesty, and trustworthy.
