  We contrast the sparticle spectra obtained from three modern publicly
available codes along model lines in minimal supersymmetric standard model
(MSSM) parameter space. From this we gain an idea of the uncertainties involved
with sparticle spectra calculations. The differences in predicted sparticle
masses are typically at the several percent-level. In the focus-point scenario,
there are differences of 30% in the weak gaugino masses. These uncertainties
need to be reduced in order to obtain accurate information about fundamental
models of supersymmetry breaking.
