We present new values for the MSˉ masses of b and c quarks based on lattice NRQCD simulations of the Υ(bbˉ) and ψ(ccˉ) systems. These include three measurements of the b mass based on quenched simulations with lattice spacings ranging from 0.05fm to 0.15fm, which we find to be largely independent of lattice spacing. In addition, we find a consistent value from an unquenched simulation at 0.08fm.
