I happen to have one brand new and one store demo Nikon D3x bodies in the store right now. I was unaware of their scarcity - because of the tsunami they are no where to be found.
The store demo has a few thousand frames on it, but would come with full warranty. That body we have listed at $7,600 + insurance and shipping. The new body in the box is available for $7,999 + insurance and shipping.
You may direct questions to me via PM on this site, by email at firstname.lastname@example.org
or may call my store directly and talk to any of my staff, Pixels Foto & Frame, 801-233-9090.
