I am interested in purchasing a wheatgrass juice extractor for personal use. I have viewed the Miracle MJ550 and the Wheatenna Green Label. I do not want to over do it however I am a great believer in value for your money. Is extra money worth of difference in the Wheatenna machine?

It depends. If you are serious about juicing wheatgrass, the Wheateena will last many, many years. The Miracle MJ-550 is a much cheaper machine. The Wheatenna is made here in the USA, with solid metal construction with a 3 year warranty. (I have even seen it used in some juicebars) The Miracle MJ-550 is made overseas, and is made of plastic. It has a 1 year warranty. It is fine if you want to do 1-3 ounces a day. If you are not sure you will stick with wheatgrass, and/or will use the machine occasionally, go with the mj-550 since it is less expensive. If wheatgrass juicing is something you are serious about, I would spend the extra money for the extra 2 years of warranty, and the more solid (no plastic to break) construction.
