For a point mutation (or a couple) the "Quickchange" PCR system works well.
I know you don't want to use Stratagene's kit... and neither do I. But you
don't need any kit to use the strategy. Read their manual to get a few
hints, and do it with your own reagents... I just sequenced 3 clones out of
8 I picked for a double point mutation (vector+insert size = 6kb)... all
three were perfect. Just one step.
For other things I use a "megaprimer" approach (google) which is another
