I was googling around and found a ZR4 advertised for sale. The site that is selling it has been around for awhile. It looks like a ZR3 with the 3 changed to a 4 by photoshop. I am wondering if they are jumping to gun on this. Also it is listed for 599, they still have the ZR3 listed for 499. We are not supposed to list links, google it and see.
