  Let M be a Galois cover of a nilpotent coadjoint orbit of a complex
semisimple Lie group. We define the notion of a PERFECT Dixmier algebra for M
and show how this produces a graded (non-local) equivariant star product on M
with several very nice properties. This is part of a larger program we have
been developing for working out the orbit method for nilpotent orbits.
