Thats about $220 to $250. make it $20-$40 for a soundcard. The OPTI931 has a street price of $20 here in italy, and CS4236 (assuming you can find them) are little more expensive. For conferencing purposes they are both more than ok (Crystal much better since it is better documented and less buggy...) > 2.
