I want to give a shoutout to a similar but much nerdier design, which is no longer sold. Kenmore (rebadged as De'Longhi) used to make a single long-slot toaster with an adjustable width all the way out to about 2 inches. I have one. The heat element isn't amazing, and it, like the Dualit, is manual lift with a timer. But critically, you can move the toaster elements manually together or away from one another with a lever on the top of the toaster. In other toasters, the elements are fixed in position regardless of the bread width. As a result, this toaster is amazing for big thick hand-cut slices of bread. And no need for a sandwich cage at all: you can put entire hoagies in there.
