I use my Kitchen Aid mixer all the time and love the sculptural quality of it sitting on the counter, but for those who don't have the counter space, consider a pop-up cabinet. Those stand mixers are heavy!
Space-Saver Appliance garages are great for stowing small countertop appliances. But make sure the doors either slide side-to-side or up and down. Swing-out doors consume the most space and tend to get in the way.
