Before committing to a side by side, take a look at the traditional freezer on top refrigerator. Top mounts tend to be more energy efficient, allow larger size storage and more storage overall. You will be bending and stretching more, however, as you search for that elusive kumquat. Many models do not have the seemingly indispensable water and ice dispenser.
Keep in mind the door clearance again, as the door is the complete width of the refrigerator and can require more space than you have in your kitchen.
