McMaster-Carr (http://www.mcmaster.com/#lapping-compounds/=1398cvu).
Their prices are in line with other quality monocrystalline compounds (as opposed to the polycrystalline "imported mystery pastes" on Amazon etc) including the Norton water-based paste that TFWW sells, but they sell a wider range of grits. Norton also makes water-based compounds in the mid grits, but TFWW doesn't carry them and availability elsewhere can be iffy.
The natural diamond powder also looks really interesting. In theory that should hold up even better than synthetic monocrystalline pastes like DMT/Norton/PSI, and should be vastly better than polycrystalline ones.
