Kitchen Aid...
My late mother had arthritis in her wrists and always had problems with her mixer...a Dormeyer..until one Christmas she asked me to set my 65 Kitchen Aid up for her so she could make cookies,after using it 1 time,she put the Dormeyer up and never used it again, the Kitchen Aid was on the counter until she passed away,the stainless bowls were much easier for her to handle, and she didnt have to stand with a spatula,I prefer a 2 beater machine for layer cakes,but overall a K.A. is superior, especially for cookies and other heavy mixtures.
