Here's the trade off: if you want a slim toaster that doesn't gobble up too much counter space, you're going to be limited to how much toast you can make. But the Easy Toaster from Russell Hobbs incorporates a nice workaround. You can only toast two slices of bread at one time, but a pair of pockets on the outside steal heat from the toaster's elements to keep your breakfast warm while more slices toast.
The £35 Easy Toaster is particularly well suited to cramped kitchens because its flat backed design means you can push it up against a wall so its minimally intrusive on your counters. Plus, its high lift feature, something every toaster should have had from day one, makes it easy to snatch your toast without putting your fingers in dangerous proximity to red hot heating elements.
