Cycloheximde/what to do now?

[Sheepskin Hollow]

We have used cycloheximde extensively in a differential/selective agar
for Campylobacter- Campy-Cephex Agar.

We now are finding that the price of the stuff has skyrocketed and I have been 
told it is no longer manufactured.

Anyone out there know more about this problem or have ideas on what
we might use for a subsititute.

Any suggestions for a substitute medium?
