On the one occasion my KitchenAid needed fixing, I went with the local
factory recommended repair place. There's one six blocks from me in San
Jose; here is one closer to you. This info comes from the KitchenAid
website.
Appliance Sales & Service Co.
840 Folsom Street
San Francisco, CA 94107

It's almost certainly a lot cheaper to get them repaired than to buy new
ones, and (as has often been discussed) the new ones are often not as well
made as the older ones.
If you decide to go with the new ones, let me know and I'll be happy to make
you an offer on one of the old ones.
