firewire ExpressCard recommendation

I want to run 2 DV cams into my laptop.  laptop has one fw port.

There was only one at my local store, and linux doesn't see it at all (nothing 
in lspci, dmesg, syslog)  The only way I know it works is because it worked in a 
mac, which gave me this PCI ID:
[197b:2380] FireWire (IEEE 1394) [0c00]: JMicron Technologies, Inc. Device

So, anyone have one they like?
