We present measurements of branching fractions and charge asymmetries for the
decays etaK*, where K* indicates a spin 0, 1, or 2 Kpi system. The data sample
corresponds to 344x10^6 BBbar pairs collected with the BABAR detector
at the PEP-II asymmetric-energy e+e- collider at SLAC.
We measure the branching fractions (in units of 10^-6):
BR(B0->etaK*0)=16.5\pm1.1\pm0.8, BR(B+->etaK*+)=18.9\pm1.8\pm1.3,
BR(B0->eta(Kpi)_0*0)=11.0\pm1.6\pm 1.5, BR(B+->eta(Kpi)_0*+)=18.2\pm2.6\pm 2.6,
BR(B0->etaK_2*0)=9.6\pm1.8\pm 1.1, and BR(B+->etaK_2*+)=9.1\pm2.7\pm 1.4.
We also determine the charge asymmetries for all decay modes.
