I bought a Breville JE98XL and I'm so happy I got it. I've been making my green juice in a regular mixer and oh my... I have been missing out! This changes the texture of the juice completely and even gives it a better flavor. I put a few strawberries and a banana for my girlfriend to drink and she loved it! (to be honest, she doesn't like everything that I give)
The build quality is pretty solid with no small parts prone to running away. Its very easy to take apart (less than a minute) for cleaning and reassemble. Its not all stainless steel or metal like some of its more expensive cousins, but the heavy grade polymer feels... well, heavy grade. The base feels stable, and I've never had an issue chasing it around the counter when its doing its thing.
P.S. I took the first reviewer I've found, and there it is an "editor's choice"
