Okki Nokki is the best -- hands down. I've used one for two years. What impressed me is that the OKKI NOKKI's arm is made of METAL. The VPI 16.5 is made of PLASTIC. The VPI's arm has a history of breaking if you press down on it too hard OR at an angle. There is a wonderful you tube video comparing both machines -- the OKKI NOKKI is clearly the better product.
