Firewire adapters

Anyone out there know if it's worth caring about the quality of PCI Firewire adapter I put in my desktop? They range from $11 to $108 or so. The expensive ones have a lot of bonus features like USB ports and Firewire 800. But I feel a little dirty buying an $11 card to attach my expensive sound interface to. Though it occurs to me I never think about the quality of my USB adapter.
