Yeah, actually I have written a few articles about it which can be found the on FacesOfJuicing.com blog, but in a nutshell:
1. You need to decide if you are going to juice or blend. I recommend juicing because it is more efficient in getting the nutrients to your body (no need to break down the blend).
2. When it comes to juicers you want something that is easy to use, easy to clean and gets the most juice possible (dry pulp)
3. When it comes to getting the most juice from your produce I have discovered that the stronger your motor, the dryer the pulp and it enables you to juice things like parsley and lettuce with ease. We have the
1200w, 5-speed Breville Dual Disk Juice Extractor. Yes, it costs more but you will save money in the long run because you get more product from your produce. Besides, I know there was little chance that I was going to pay $500 for something and have it just sit on my counter.
4. I have used a lesser powered 800w Breville juicer and broke it because I was using it like a 1200w juicer, it was not capable of handling an uncut apple. I would never use less that 1000w. I read of lots of stories of people breaking their juicers shortly after purchase, so spend the money and buy just one in stead of 2, 3 or 4 before you give up.
