  The modern precision accelerator data has essentially ruled out the most
obvious model of dynamical electroweak symmetry breaking, technicolour. The
idea is though well motivated and it is important to construct models
compatible with the precision data of this ilk to motivate experimental
searches. We describe the top-see-saw and flavour universal symmetry breaking
models that break electroweak symmetry dynamically yet have a decoupling limit
for all new physics. Limits on the scale of such new physics may be placed
using precision data and direct search results from the Tevatron.
