i have one, this is dgx i think. lots of reviews online, and they have everything down from $20 i think up to something more expensive than a complete basic rig if im not mistaken. so whatever it is, im sure they have what you want.
even the latest (the last ive read at least), recon model was it, from SB, i did not like it, it was more of a gimmick, not much improvement. if i remember it right.
go check out asus's site, at first i was also skeptical, asus wasnt known for sound cards, but surprisingly they have pretty good stuff, well worth it
