This site notes it's possible to buy deeply discounted (e.g. $300), reconditioned Vitamix blenders with a 5-year warranty. I hope it's okay to post this link; the blender info is at the bottom. Using her link gives you free shipping.
I have no affiliation or experience with that site, with Vitamix the company, nor their blenders. It just sounded like a good deal that might be of interest. http://blog.fatfreevegan.com/2013/11/spaghetti-squash-pesto-lasagna.html
