Well, you can reproduce the same process by using a champion juicer, which is the same cold grinder and runs about $200 and get a hydraulic press for $150. I think you can get them at the gerson institute website. Then buy filter cloth bags from the Norwalk people and you are ready to go. The hydraulic press is good because you will get more juice out of the pulp than just using a regular champion. But the champion by itself will give you the same qualtiy as a norwalk.
The produce is more expensive than regular food though.
