Strange you should mention that, because just yesterday someone showed me a

paper that claims 58-97% mutagenesis with a single primer, no subcloning,
no special vectors, and no nucleotide analogues.

The reference is Lai et al, (1993) Nuc. Acids Res. Vol.21, No.7,

The method involves a very clever trick using 3 pre-existing restriction
sites (none of which are lost) and a varient of the gapped-duplex method.
I personally have not tried this (yet), but I have second-hand information
that it works as well as it claims.
