The SB0460 is what I own. It's sold as a bare card (might come with the drivers CDs like it did in my case), but it's the same card you'd find in the retail boxed version. The software that you can get from the Creative website work with it without a hitch (the ones on the CD are too outdated to work properly with Vista). Mic input works perfectly.
Frys had a firesale on them a few months ago (for a bit less than that eBay price actually...), and I haven't seen them since.
