In minimal SUSY-GUT models with MSUSY ≲ 1 TeV, the renormalization group equations have a solution dominated by the infrared fixed point of the top Yukawa coupling. This fixed point predicts mt = (200 GeV) sin β; combined with the LEP results it excludes mt ≲ 130 GeV. For mt in the range 130-160 GeV, we discuss the sensitivity of the mt fixed point result to GUT threshold corrections and point out the implications for Higgs boson searches. The lightest scalar h has mass 60-85 GeV and will be detectable at LEP II. At SSC/LHC, each of the five scalars h, H, A, H± may be detectable, but not all of them together; in one parameter region none will be detectable.
