We consider non-supersymmetric four-dimensional closed string theories
constructed out of tensor products of N=2 minimal models. Generically such
theories have closed string tachyons, but these may be removed either by
choosing a non-trivial partition function or a suitable Klein bottle
projection. We find large numbers of examples of both types.
