There are only five of us, five collectors in the world with over a hundred pieces. We're all great friends and get in touch with each other almost daily, sometimes just to exchange opinions or share our enthusiasm about a new purchase.
The number of new collectors is currently on the increase (a few hundred enthusiasts who own from 5 to 10 espresso machines), especially in northern Europe, Asia, Australia and the United States.
This kind of collecting is more recent than coffee makers for home use, which people have been collecting for many years now.
