  We use ISAJET to perform a detailed comparison of the supersymmetry reach of
the current Tevatron (100~pb$^{-1}$) with that of the Main Injector
(2~fb$^{-1}$) and the proposed TeV33 upgrade designed to yield an integrated
luminosity of 25~fb$^{-1}$. Our analysis is performed within the framework of
the minimal supergravity model with gauge coupling unification and radiative
electroweak symmetry breaking. For each of these three luminosity options, we
delineate the regions of parameter space where jets plus missing energy plus 0,
1, 2 (opposite sign and same-sign dileptons), and 3 isolated lepton signals
from the cascade decays of sparticles should be visible above standard model
backgrounds. We compare these with the parameter regions where signals in the
clean isolated dilepton and trilepton channels (from chargino/neutralino and
slepton production) should be observable.
