Hot subdwarfs are variously associated with the extreme horizontal branch and helium main-sequence, as well as other low-mass stars evolving to become white dwarfs. About 10% have partially or extremely helium-rich surfaces, with highly heterogeneous properties. Using the Southern African Large Telescope, a spectroscopic survey was begun to search for and analyse new members of various subclasses. With over 500 stars observed to date, we have discovered extreme helium stars, heavy-metal subdwarfs, super-hot pre-white dwarfs, a planetary nebula, a compact binary, and magnetic subdwarfs.
