Check out John Kohller's videos. He has a store Discountjuicers.com but he is really honest about the pros and cons of each juicer http://www.youtube.com/watch?v=FXPuH0s8I0A
I couldn't decide what to get. I actually wanted both a high quality blender such as a vitamix AND a juicer...I couldn't afford both so I had to decide which one to get first. I chose to get the JUICER first because the thought of drinking savory or sour smoothies freaked me out and I wanted to be able to have JUICE. I still can use a cheap blender to make fruit smoothies and add kale juice to it if I want a green smoothie. I chose the omega 8006 juicer and I'm super happy with my purchase. It's a fabulous juicer for the money and it has a 15 year warranty.
It is the best juicer for greens and does a good job on other vegetables and fruits as well. It is super quiet. I also love it because it is a muli-functional machine. It comes with a blank plate that allows me to easily grind garlic, ginger or spices. It also makes nut butters, almond and coconut milk, AND it comes with a pasta attachment so it will extrude pastas. Something I'm really excited about since I want to experiment with non-wheatbased pastas. My FAVORITE thing about this juicer, OTHER than the juice of course, is the frozen fruit sorbets. I made watermelon sorbet, banana-blueberry sorbet, mango sorbet. YUM YUM. You just freeze the fruit and pass it through the juicer and out the pulp ejector comes the most fabulous frozen treat you can imagine! You'll never need ice cream again! I used this juicer for my 30 day juice fast, and I used it EVEN MORE after my fast. I use it to grind my garlic and ginger for my meals, I also use it to make the frozen sorbet desserts.. which definitely helps me with a healthier lifestyle.
No one juicer/blender can do everything. There are tradeoffs of course, but the Omega 8006 was right for me. I don't know if it's right for you or not. I encourage you to check out john's videos and see.
