We review the connection between mt and the Zbb̄ vertex in ETC models and demonstrate the power of the resulting experimental constraint on models with weak-singlet ETC bosons. Some efforts to bring ETC models into agreement with experimental data on the Zbb̄ vertex are mentioned, and the most promising one (non-commuting ETC) is discussed in detail.
