I have been using the LocalDirector for a couple of years with great
results.  Get two for failover if you want.

Make sure you understand the concept behind what it is doing ( for
whatever you chose).  The localdirector acts a bridge between two vlans
on your switch.  so you have vlanALL and vlanSERVERS . if the
localdirector is not there, no traffic can get to $SERVERS at all. hence
buying two, "just in case".

Let's face it, there's no Hollow Earth, no robots, and
no 'mute rays.' And even if there were, waxed paper is
no defense.  I tried it.  Only tinfoil works.
