Hi,
You will want to check this
resource. The appliance web link is a forum where the people are as obsessed about their kitchen appliances as we are about the Chicago restaurant scene.
I am also a fan of Consumer Reports, which may have some information on your deLonghi.
I own two 5-quart KitchenAid Stand Mixers. One I bought new 25 years ago, which required one repair about 15 years ago. It has metal gears, an important feature not found on all KitchenAid stand mixers today.
My second 5-quart KitchenAid is considerably younger and inherited from a friend. This model has plastic gears, which were stripped when she kneaded bread on too high a speed. The cost of the repair is $89 and the repair station is in Hoffman Estates. Since old reliable works, I have yet to bother to fix this one.
It is my understanding the 'Professional' labeled KitchenAid mixers have the metal gears. Other KA models have plastic gears. When I bought my older mixer years ago, all KitchenAid mixers had metal gears.
If I were in the market today, I would either buy the Professional KA or wait until I found an older model, which are always available on e-Bay. I have given my three sisters all 4.5 quart older models. The avocado green colored KA got the quilted cover for aesthetic reasons only.
I just took a look at your suggested model, it looks like the Kenwood I was considering long ago. Back then, the Kenwood was made in England and somewhat more expensive than a KA. In one auction on ebay, they referred to the Kenwood as having the same lineage as the Delonghi. When it comes time to repair, I will suggest the KitchenAid parts will be easier to obtain. Plus the KA has a lot of interesting accessories, which you may want later on.
Regards,
