Help needed to buy blasticidin S

[Wenjin Guo]

Hi there:   I am looking for a antibiotic called blasticidin S which could be
used as a selection marker for fungal transformation.  The only place I can 
find
to sell it in the US is ICN. Their price is very expensive ($69/25 mg) and they
charge $25 for shipping.  Anybody has the idea where I can get a cheaper price?
How is the quality?

Thanks a lot. Your help is highly appreciated.
