im running windows (only because im too lazy to upgrade to something decent).
newegg and ebay were both pretty bare, at least in the price range im looking for. the only one on newegg only output stereo sound through the coax out, and the rest there were over 150. ebay just seems sorely lacking in sellers who know what they're talking about, and i havent been able to find much of anything searching for coax out or s/pdif.
