I have bought reconditioned, it is usually as good an new or better since it has been tested throughly by the company.
The only problem I have found with Dewalt is the electrical cords. The Dewalt items I have owned the outer sheathing cracks and splits over a short period of time. Dewalt does not warrenty it. In fact they will never answer your mail or email concerning this either. Dewalt is part of the Black and Decker Company along with Porter Cable. So I just buy Milwaukie. Which I think is a better tool.
