I love my hand crank VDG. I have this one from Arbor http://www.arborsci.com/detail.aspx?ID=559 and it makes sparks a couple of inches and has no problems raising the hair of even wavy haired students. All the parts are clearly visible and without a connection to the wall, no one thinks that it is wall current doing the work.
