Hello, I have a juice man jr and want to up grade. I am haveing trouble decideing between a champion and green star. I would appreciate the benefit of your experience with these juicers, concerning quality of juice, cleaning time and difficulty, noise and time it takes to juice 16 oz of carrots. I plan on juiceing fruits and vegetables as well as wheat grass. I have been juiceing for aprox. 6 months and figure I am 70% raw food diet. I have lost weight, although that was not a goal for me. I am simply amazed at my energy level. Just though I'd throw that in. thanks ron
