In the film about the juice fast, he uses a Breville and it has great reviews and comes in a variety of models to suit every budget. I ordered the Breville Die-Cast Juice Fountain as an early Xmas gift for our family from my parents, and we found it for $269 online, no tax and free shipping. It's usually $299+ elsewhere. There's another model that runs under $200 which is also very good. These two are the cheaper ones that juice only, with the pulp extracted. Then there are models that can either juice or make smoothies using the whole fruit, but I already have a Vita Mix blender for that, so I went for just juice.
My brother made me a delicious juice the other day. It was kale, apple, carrot, lemon, ginger. Delish! I have no idea what proportions he used, but once I start playing around with it, I'll post my favorite combos with quantities!
