As silly as it sounds, toasters are one of the most valuable items in Arc Raiders. Or, at least your first three as they're used to upgrade the Refiner back at your workshop. Since the Refiner is used to craft certain higher-quality upgrade materials, like advanced mechanical and electrical components, levelling this station up should be a priority early on.
For the level two Refiner, you'll not only need three toasters, but also five Arc motion cores and eight fireball burners. Luckily, the latter two are found on Arc machines—fireball burners specifically from Fireball Arcs, of course. Toasters, however, aren't so simple to track down.
