We present results from various programs studying the halo kinematics of nearby galaxies. These include more extensive planetary nebula (PN) data and updated mass determinations of the "ordinary ellipticals" recently found to show little trace of dark matter. Our globular cluster study of NGC 3379 independently confirms the low halo mass of this galaxy. PN measurements from a larger galaxy sample show weaker rotation than expected from galaxy mergers. We also present 2800 PN velocities around M31, and from these data infer a dynamical connection between the halo stellar streamer, the northern spur, and M32.
