I use my KA mixer all the time, and not just for mixing. I've got a lot of the attachments that I use as well.
To be honest, I would use my food processor to make food for our parrots more than anything else. They're on a specialized diet of cooked legumes, sprouted grains and finely chopped veg and greens. Since I've got a couple of picky eaters, I would run the legumes through the food processor to mix them up and create a mush out of them. That way they can't pick out just the ones they like. Then I run the veg and greens through and mix all of that together with the grains.
So I need one that will stand up to that kind of abuse. And I need to get over being an old fudd who likes a food processor that sits next to the motor, not sitting on top of it....lol
