My sister raves about the nutri bullet. It is an extractor that leaves the nutritious pulp in the drink. Her kids are even drinking smoothies made with spinach. She said she got it at target for 100 dollars. You can watch infomercials online about it. There are lots of copies so beware so that you get the one that is actually a juicer and not just a mini mixer.
I have a ninga that is very powerful but never tried to use it as a juicer.
