Any recommendations for PCI rs232 card?

[scifiwasabi]

I'm wanting to put a RS232 PCI card into my desktop. It will be running windows xp pro sp2 or sp3 depends on how the card reacts i guess. I was wondering if anyone has any suggestions or recommends a certain card. Or has had issues installing one or using an addon card with AB or Siemens products (I will be using mostly AB stuff though). Thanks

edit* oh, it has to be PCI not PCIe
