I have been one year in therapy supervised by Gerson clinic. I have the Norwalk at home alright but when i travel in a few days trip i use cheap juicer as well.
If you do not have serious illness I guess some juices are much better than none especially if you do the juicing yourself compared to buying it from somewhere else.
I have heard good comments on the Green Star juicers but I have not tried them. A friend of mine who tried green star told me it was good. Not sure if it good enough for cancer though. He also tried another Hurom from Korea and gave a good feedback.
