Hey guys, I really need to buy a food processor (most notably so that I can make my own hummus, because it's so tasty and why spent $3 for a tiny container when I can just make my own?)... Alton Brown says to get at least 650 watts, but other than that I only know it need to be able to pulverise garbanzo beans and occasionally cut veggies, but I DON'T need one that does dough (I have a Kitchen-Aid stand mixer for that). Any recommendations?
