We had a Cookworks for many years from Argos which worked really well (and still works well as a second toaster). Have just brought a Prestige for the simple reason that the elements are close together and evenly spaced.
This has replaced a Russell Hobbs which was frankly terrible, it toasted unevenly, burnt toast if used a few times in a row and although it is only 2 years old the rack doesnt always stay down . The elements are so uneven with some flush to the surface and others sticking out its no wonder it toasts unevenly.
