Get a vitamix or blendtec.
Whatever you do don't go near a ninja.
For serious blending you want something with at least a 2.0 HP moter.
Juicers are so inferior in every way .
Hard to beat vitamix but there are a few other decent brands but go to any smoothie store and they all either use vitamix or blendtec
I like the vitamix over the Blendtec. No digital lights or bells and whistles just a bad ass blender. I swear I could put rocks in there and pulverize them into powder.
