Does your notebook have any cardslots? I'm not sure of the technical name, but if you've got the slot, you can buy a firewire card that just pops in there and then you can plug it in.
I had one a while back, it didn't work too well for me, but I think that was more the fault of Windows Movie Maker not being able to handle it. Or maybe it was my processor.
I've only heard horrible things about firewire to usb adapters.
Do you have any desktop at all in which you could install a true firewire card and just use that as an import hub? The cards are under 10 bucks and easy to install, that would be my #1 choice.
