I found an excellent article on the comparison of juicers. Refer to the article below. I'm also in the market for a new juicer and while price of course is always a factor, one has to always weight the benefits/cost relationship. As you well know not only in juicers, but with many products cheaper is not always better. But, the bottom line is to make the juice and DRINK IT! I think if you are really serious about getting into juicing
and plan to do it everyday, it would be a good investment to get a good quality juicer. If you get a trituator juicer and then juice non-organic veggies and fruits does it make sense? Likewise, spending a lot on organic food and then using a cheap centrifugal doesn't make sense either. Therefore, it is all going to depend on what your goals are for your "juicing" health.
Keep healthy and God Bless....
