Hi Audrey,
I saw your post inquiring about the Kitchen Aid mixer and I want you to 
know that you don't have to worry about the motor burning out.  No ma'am, 
the gears will strip out first.  I have one and they've wiped out twice at 
$100 dollars a pop to get it fixed.  The second time I pitched it in the 
junk heap and bought a Bosch Concept7.  I couldn't be happier.  It's a 
dough kneading fool.  As far as I'm concerned, the KA is just a toy if 
you're a serious baker.
According to reputation, the Magic Mill DLX is good.  Bosch Concept7 or 
Universal are both good.  The Kenwood KM800 is good.  I haven't heard 
anything about the Whisper Mill 2000.
Buy a Kitchen Aid and your small appliance repair guy will love you.
Don
