We use Promega's Altered Sites kit and always obtain good results.  You
have to use the single stranded DNA protocol, though--us and several
other labs haven't had much success with the "new" method.  This kit
requires youy to clone into pAlter, but I think they're coming out with
one that doesn't require additional subcloning.

We get between 50-90% mutagenesis about 98% of the time.  We've made
maybe 50 mutants this year alone, and only one didn't mutate the first
try (second try worked, though).  Very rarely fails us.

(no affiliation, just a happy customer).
