I keep burning out my blenders after a couple of weeks. I'm not sure if it is grinding the oats, or blending the peanut butter into my shakes, but $40 blenders are not lasting me a month. Anybody got a good recomendation for a food processor that can withstand that kind of daily use. I figure if I buy it during black Friday sales I will get the most bang for my buck, so I'm kinda under the gun here.
