$44?? That's incredible value for money for a 90dB-snr sound card.

I've been using an Event Gina card for some time now, and I must say
that it is surprisingly quiet. The designers have paid a lot of
attention to grounding and shielding through the multilayer board,
it seems. Remember, the inside of a PC is full of broad-band RF
fields, and you still have to keep SCSI cables and other noise sources
off the board for best performance.

Have you tried Integrated Electronics (Crystal's Finnish agents)?
