Hi- I got a juicer for Christmas and LOVE it. I don't juice daily, but a couple of times a week. I think in summer I'll juice more, but here in CO produce is still pretty pricey since we're just getting out of winter! I juice whatever is around or in season. My favorite is apple, pomegranate, blueberry, and carrot.
There is a book called The Juicing Bible, it has tons of recipes, and geared toward your goal- weight loss, arthritis, headaches, etc.
And I have the Omega VRT juicer. It's amazing. Wasn't cheap, but I think you get what you pay for in these- especially if she will be juicing daily.
