Recommend a Firewire PCI card

My film scanner (a Coolscan 9000) has been hanging oddly when I scan medium format film using a certain film tray - always and only at frame 2 or 3.

It has been suggested to me that I should try with a separate FW card instead of using my Mac Pro 3,1's FW connections (the hang appears regardless of which of those connections I use). The scanner uses FW400.

I would be grateful if someone could recommend a FW400 PCI card to me. I had a look here in the Netherlands and found mainly cards from manufacturers I'm unfamiliar with (here).

Thank you in advance

Philip
