what sound cards can the Audigy2 Platinum plug up with?

I've got an Audigy2 5.1 platinum interface but dont have a sound card compatible with it. I know the $70 Audigy2 will plug up fine but is there anything cheaper? The Sound Blaster Live card i can get for $30. Doubt it can plug up though. Not looking for the best. Just something that works.

I'm also a college student with $60 in his pocket at the moment ;)
