Other issue is cleaning. If it isn't a modular one where you can remove the blade area from the motor and stick it in water (or at least run it under water), you'll get dust from previous uses building up. Usually it's difficult to get under the blade to scrub.

Though on that note, I'm going to try avoiding buying any kitchen appliances that won't allow you to soak or rinse the parts that come in contact with food. This includes blenders/grinders as well as appliances like the Foreman grill. My current one gets a lot of use but cleaning it is a pain. It will soon be replaced by a modular one where the plates can be removed entirely, which will also mean that the new one will take over for my waffle maker, which is the single worst appliance for cleaning.
