I first bought a cheap centrifugal juicer to try out juicing, I think it was an Oscar or something. It was hard to clean and wasted produce so I rarely used it. Juice seperated after sitting like all centrifugal juicers.
Then I bought a jack Lalanne juicer. I thought it would be great because Jack said it was top of the line. It wasn't much better. I rarely used it and the cheap plastic bolt on the motor housing broke.
Next was the Omega Vert HD Juicer. Better quality juice. Much easier to clean. Juices greens also. Too much pulp. You have to feed it just right or it will clog. Anything stingy like Celery will clog it unless cut up into small pieces.
Finally I wised up and got the Omega 8004. Easiest machine to clean. Better on greens than almost any machine. Less pulp. Full bodied juice. The screen is very small so it is easy to clean.
Recently some technicians screwed up and re heated left over plastic when making the screen part and caused a problem . It doesn't matter because their is a 10 warranty on manufacture defects.
Now I bought a Vitamix and like it equally well to the Omega 8004. You can do much more with it.
