Thanks for the input so far! I'm mostly torn because my food processor is starting to get a big crack down the side so I will most likely need to replace that, too. If the Vita-Mix will do both jobs, that would be great - it would open up my counter space to have only one machine there. But if the Vita-Mix can't do hummus I will definitely need a food processor because I make hummus all the time.
I mainly want a blender to make smoothies, shakes, nut milks, and to puree ingredients for vegan ice creams (such as nuts, fruits, etc). TNS - what you say about the Vita-Mix turning things so smooth and creamy makes me think it would be a great machine for prepping ingredients for ice creams.
So -- I need to decide whether to spend $350 on one Vita-Mix or on BOTH a high-quality blender and food-processor. Sounds like I could still get some very quality machines and my total bill would be less than the price of the Vita-Mix. Decisions, decisions!
