I really love mine. It is heavy, so sits on the counter with a placemat under it so I can push it around. It gets used several times a week - great for kneading bread. I have the strainer/grinder attachments and use them a lot for making applesauce and tomato sauce - no need to peel or core. For applesauce, I cut the apples into 's, cook until soft, and run them through the KA -done!
For tomatoes, just slice in half (to prevent them from squirting all over the place when you push them through - like on my white ceiling - and then cook down to the consistency you want. If you have a lot of cherry tomatoes, it makes quick work of them, since you don't have to peel all those little things.
I also have the slicing attachments, but they aren't very sharp (something like celery ends up being a stringy mess), so I don't use them much.
