The centrifugal juicers are not good. Dr Gerson uses the Norwalk juicer, but this is way overpriced. I have been looking at the Champion juicer and the Samson juicer and will be purchasing the Samson. Dr Gerson believes in using a juicer to remove the fiber so that the fiber doesn't fill you up, and thus you can drink more juice. The Vitamix I have is gret for protein drinks but over oxidizes fruits and vegetables.
