Jcomiot - don't bother. You sound like you've found a "great deal" and you are considering it. If you want a D7000, you will either pay at or damned close to full retail MSRP. If you see a D7000 new sold for $700 on Somethingxx.com, it is FAKE. There is NO such thing, for example, as a $700 D7000. Stick with the known good guys, Adorama.com, KEH.com, BHPhoto.com, etc.
I didn't bother. I already bought from BHphoto. Now how can I tell I have the real thing. Or is their word good enough?
