Turtle Beach Santa Cruz Videologic Sonicfury Audio
As I understand it, Turtle Beach and Videologic have come to an agreement - they're selling the same card (though under different names) and each is selling it in different markets. Videologic are the ones selling to the Australian Market - as Turtle Beach has little presence here - thus you won't find the Santa Cruz many places (unless it's imported directly) - and instead you'll find the Videologic SonicFury.
The SonicFury and Santa Cruz are identical - and you can use either Turtle Beach or Videologic's drivers. I bought a SonicFury myself the other week for $210 and I'm using the latest 4112 Santa Cruz drivers on Windows XP at the moment and I'm pretty happy with em! Practical upshot of this is.
Look for a Videologic supplier! For one it doesn't corrupt your hard drive data, cause sound popping, skipping, etc like the SBLive does! Seriously tho. It's probably not a serious musicians card - there's no optical ins or outs, and only one spdif out (digital out via the versajack) and no digital in's. The Hercules GameTheatre XP is probably a bit better in this regard - it has midi ports and digital in/outputs on the main box - and it's based from the same chipset.

It's also a hundred bucks more, and you've got a whopping great box to lug along to lans - but it's got show value too I guess.
