Typical search limits for pp colliders are ~0.25-0.30 times sqrt{s} assuming 100 fb^{-1} to 1 ab^{-1} of integrated luminosity with some variation due to differences of fermion couplings in the different models. Discovery limits at the Tevatron are ~1 TeV for 15 fb^{-1}, approximately 30--50% higher than this rough guideline, due to the higher q\bar{q} luminosities in the p\bar{p} beams.3 pages, 1 figure.
