The good news is that other gelling agents are available.  The bad news
is that agar is about the cheapest one.  In addition, organisms exist
which can degrade all gelling buffers (although no one organisms of
which I am aware can degrade them all).  Starch, gellatin and "gel-rite"
can be used to make media.  If you can't afford agar, then it is time
to start filling out those grant applications!
