The Survey of Nearby Nuclei with STIS (SUNNS) is exploring the nuclei of an approximately volume limited sample of 24 bulges that show nuclear line emission. The increase in spatial resolution (compared to ground-based data) also provides drastically improved suppression of the stellar bulge light.We will present newly discovered BLRs in very low luminosity AGNs, clearly attesting to the presence of a black hole. We will also present black hole mass determinations from H\alpha velocity fields in a subset of six galaxies.
