Make no mistake: A Vita-Mix 5200 blender is overkill for the home kitchen. It's $450, to start. And its laudable blending ability doesn't even make itself apparent unless you're blending quite a bit of food at once. But over the course of the last month, I've yet to find food it can't turn into a healthful slop—eventually.
(You can buy a smaller blending carafe that makes it more suitable for home use, but that'll set you back nearly another $100.)
