I have a Blendtec, it's worth every penny. I keep big bags of frozen fruit to mix with Whey Isolate, that makes a quick meal substitute. I use 2 kale leaves in most drinks, so they don't taste to good. I do all green drinks too. It's not expensive when you think about how much each drink would cost over a year. And most important, I buy the best vegetables and the most expensive whey. I don't think stores would spend the extra cash on ingredients.
