I use the ones from http://www.byterunner.com/ specifically from this page: http://www.byterunner.com/byterunner/new_frontpage=serial_parallel_cards You will want the ones noted as 32-bit PCI cards. I am using a PCI-400-HS-9. That card has a 'spider' cable which branches out to 4 9-Pin DB9 connectors. The computer I am using this in has 1 built in serial port, bringing the total to 5 usable serial ports with this card. It's worked well for me.
