I agree.  If you want the best of both worlds you could add the above
as forwarders.

ie. The caching name server will first look in its own cache.  If not
there it will ask one of the forwarders instead instead of going
directly to the office source for that domain.  It is really easy to
add forwarders with SUSE via yast.  I don't know about other distros.

As to maintenance, zone files etc. can be difficult to maintain, but a
caching only server has never given me any issues at all.  Simply set
it up and forget it.
