The QuickChange kit from Stratagene works very efficiently (90%+ for point
mutants, 50%+ for deletions of up to 1 kb and insertions of up to 100 bp).
As there were some backorders with the kit we were forced to discover (we
would never think of not buying the entire kit on our own...) that the
method works fine with Pfu purchased separately from Stratagene or Promega
and DpnI from just about anybody. Once I've used Pwo instead of Pfu and
that worked too. The largest plasmid I ever used with this protocol was 7
kb long. Let me know if you have specific questions about particular type
of mutations you want to introduce. Overall this is by far the easiest and
most efficient SD mutagenesis kit we have used.
