I summarize work done with Khalil Bitar1 on computing the lattice Higgs mass bound with three different cutoff schemes. Within the approximations we used, we find a 20-30 percent ambiguity in the mass bound from cutoff effects if the bound is obtained from the region where the correlation length is of order unity in lattice units.
