  We report three new accurate mass measurements for the supermassive black
holes hosted by the early-type disk galaxies NGC2787, NGC4459 and NGC4596. The
targets were selected from a larger set of long-slit spectra obtained with the
Hubble Space Telescope as part of the Survey of Nearby Nuclei with STIS
(SUNNS). They display symmetric gas velocity curves that could be modeled as a
rotating disk in the joint potential of the stellar bulge and a putative
central black hole. They also show regular dust lane patterns that could be
used to infer the nuclear disk orientation. These three galaxies fall in the
black-hole mass vs. central stellar velocity dispersion plane in agreement with
the recently reported relation between these two quantities.
