There is an article in First magazine on juicing. They say the Hamilton Beach Big mouth jicer is as good as the expensive ones. It is $79 on amazon.com; unfortunately more in Canada.I got one for $119 at Canadian Tire today.
I have an Omega 8006, $300 @ Amazon. Love it.
I use lots of kale, carrots, apples, ginger, lemon, daikon, sweet peppers, what ever looks good to me. I cut up the carrots and apples, but the kale can go in big end down one after the other, it's really quite fast and makes delicious juice. I make enough for a couple of days put it in a glass jar in frig.
