Here are links to everything you need to get started or continue down the path to better health through juicing:
I have found that Amazon almost always has the best prices on new juicing equipment, but you might also consider eBay or Craig's List if you are in the market for used juicers or blenders.
Juicing equipment can be expensive, but when shopping for juice extractors or a juicing blender for your home, you really should think of it as a long-term investment. It is, of course, an investment in your health, but as soon as you start juicing, you will quickly learn that the quality of the juicing equipment you choose truly does make a difference in your daily juicing experience. In fact, if you start out with a low-end juice extractor that has multiple parts to clean after every use and laughs at you every time you try to juice leafy greens, you might end up so discouraged that you give up on juicing completely.
That almost happened to me. I had a low-end Hamilton juicer that worked okay for the occasional carrot juice or fruit juice, but I was so frustrated with the amount of prep required before juicing, the number of parts I had to wash after juicing, and the lengths I had to go to to get any juice out of kale or spinach that I found myself juicing less and less. I finally decided to take the plunge and invest in a Vitamix blender, and now making fresh, homemade juices and healthy smoothies (as well as tons of other magical things a Vitamix can do -- like make hot soup!) requires practically no prep and only about 30 seconds of post-juicing cleanup.
I'm not saying that everyone should run out and buy a Vitamix, particularly since quality juice extractors definitely have their own benefits (and I'd like to eventually have both), but I do want to encourage you to not cheap out too much on your juicing equipment. If your budget will only allow for a lower-end juicer at this point, that's okay. You can find tips on maximizing the efficiency of cheap juicers online and will be able to experience the healthful benefits of juicing -- just don't get discouraged, and know that your juicing experience will improve when you are in a position to upgrade!
