"In most cases a Nikon Factory Demo is a unit that has been used as a Nikon display piece or as a "Salesman's Sample". They have never been owned by a consumer and have minimal to no use. Each unit is individually checked and tested before it is shipped to us from Nikon. Where some may have small marks or slight imperfections in the finish, it is important to note that the unit is in brand new operating condition and is covered by Cameta Camera's warranty for one full year on all parts and labor." yay or nay? seems to me that this has an advantage of buying used because its probably seen less use, its checked and tested at Nikon, and it has a 1 year warranty. My experience with this camera + current lenses I own + my budget make a D50 the perfect choice for me.
