I got a Vitamix last Christmas. It's pricy, but brilliant. In seconds it will pulverise entire fruits into liquid - literally no bits. The blades are slightly blunted so it smashes the heck out of them. You can put raw vegetables in with some stock and because it spins so fast the friction will turn it into hot steaming soup in five minutes. Sadly I mainly use it to make blended margaritas but it does make excellent smoothies too. Washing it is easy as well - half fill it with cold water, add a drop of washing-up liquid and blend for ten seconds. Clean. You can even put roasted peanuts in it and in less than a minute have delicious peanut butter. Highly recommended!
Old post I know, but are there any cheaper recommendations than a Vitamix? I just can't stomach (hurhur) the cost of one.
