I've had a Vitamix for at least a dozen years, and it is still going strong. I also have a Breville juicer, which I really like. Before getting it, I had a Juiceman Jr (which didn't extract as well as I'd have liked) and a Green Power (excellent juicer but was a pain to clean.) The Breville juices well and clean-up is quick.
I am drinking fresh squeezed juice right now and I have to say that using a juicer has allowed me to obtain nutrients I never would've gotten without juicing. they're great for people who don't eat alot of raw vegetables.
I currently use a Breville, they make quality juicers.
