Hmmm.
Have you already got a magimix?
If so, you don't need a Kitchen Aid, and a breadmaker would be fab.
If no magimix, get one of those instead of breadmaker OR Kitchen Aid.
(if i am right in thinking a Kitchen Aid is an original-style food mixer?)
A magimix is far more practical for lightening speed cake-making, also grating 6 tonnes of cheese when you have the whpole class in for baked potatoes on bonfire night. You can also use the dough hook on a magimix to get as far as that with bread-making.
then save up for a bread maker.
