I have an Ankersarum. It is comparable to a Bosch for bread, but also does all the things a Kitchen Aid can do and more. It is more expensive than all the options, but it is made with metal gears and proper belts and won't break. They also can be repaired, unlike Kitchen Aid. It has a HUGE capacity.
I have several the attachments that are available for them. One is for saucing fruits, including tomatoes during canning season (no need to blanch and peel and have a separate saucer machine). It also makes apple sauce, and strains berry juice to make jelly. Add a thing onto saucer and it becomes a meat grinder and a sausage maker. Another attachment is a shredder. Then there is a blender attachment (works as well as a vitamix just a smaller capacity). There are a couple more I don't have beyond that but I don't remember them. And the bread mixing bowl is separate from the bowl you use to mix cakes and cookies and whip egg whites, etc. I personally think it does a better job than Kitchen Aid with the cakes/cookies because the beater actually gets down into the bowl better.
But it is probably more machine than you are looking for.
