nice, you got a deal as they say. maybe there's recall on the serial # ??I just took the unit out of the box and I'd be rather surprised if it was a refurb. The box itself is the original box, including the original sticker with the unit's serial number on it. The documentation appears to be factory sealed, as do the accessory packets with the cords and such. The unit itself is in pristine condition with no signs of even minor handling. Plus, it has the manufacturer's original calibration and test report dated 01 Aug 2012. None of that makes it impossible that this is a refurbished unit, but I think it makes it highly unlikely.
