I usually set up slave (secondaries); it works well.

But if you rarely manually update it and you don't have very many zones
(and zone entries) to manage, then continue to do it manually.

As an option: some admins use rsync (via ssh) to do their updates.

There are also other things to consider:

Do you have a firewall in between the two nameservers?

Or what if your master server is unavailable for longer than the
secondaries' zones' expirations?
