External/ExpressCard 5.1 Audio Solution for MBP?

[LoneWolf121188]

I have a 5.1 speaker setup that I'd like to connect to my MBP. Does anyone know of a good external device or ExpressCard that provides 5.1 output? Creative doesn't look like they support OSX...

I just got my Griffin Firewave in the mail yesterday to do just this, and it seems to be working okay.
