Seventeen accreting neutron star pulsars, mostly high mass X-ray binarieswith half of them Be-type transients, are known to exhibit Cyclotron ResonanceScattering Features (CRSFs) in their X-ray spectra, with characteristic lineenergies from 10 to 60 keV. To date about two thirds of them, plus a fewsimilar systems without known CRSFs, have been observed with Suzaku. We presentan overview of results from these observations, including the discovery of aCRSF in the transient 1A 1118-61 and pulse phase resolved spectroscopy of GX301-2. These observations allow for the determination of cyclotron lineparameters to an unprecedented degree of accuracy within a moderate amount ofobserving time. This is important since these parameters vary - e.g., withorbital phase, pulse phase, or luminosity - depending on the geometry of themagnetic field of the pulsar and the properties of the accretion column at themagnetic poles. We briefly introduce a spectral model for CRSFs that iscurrently being developed and that for the first time is based on thesephysical properties. In addition to cyclotron line measurements, selectedhighlights from the Suzaku analyses include dip and flare studies, e.g., of 4U1907+09 and Vela X-1, which show clumpy wind effects (like partial absorptionand/or a decrease in the mass accretion rate supplied by the wind) and may alsodisplay magnetospheric gating effects.
