Get a Pisang Ceylon or Pisang Klotek, they're the same thing as Mysore but without the BSV issues (that can spread to your other plants and cause trouble).

Drop him a line and you should be able to get your hands on one. It says that he has Pisang Ceylon available right now, I would ask him about that. Here's his website:
