Graupner makes one. I don't know if it is sold in the states. I think it is the 180 speed. I have put one in a DD and it lines well with small groupings, but doesn't the torque of a Faulhaber. There is Micromo in the states and they sell Faulhabers. Portscap is in the states too and make good motors in that size. The best in my experience is the Faulhaber.
