Electric Lead Pointer (Sharpener)

Does anyone know of where I can purchase an electric lead pointer (sharpener)?

[[http://leadholder.com/assets/point/kroy/pierce-kroy-elec.jpg|Here]] is an old version that Doyald Young uses in [[http://youtu.be/PSSztlMjZtM|this video]] (at 15s). That one is a bit old. It was made in the 70's thru the 90's. I'm looking for a more modern electric lead pointer.
