Thanks for the replies! I would definately have chosen firewire over USB 2.0 if I could but my laptop doesn't have firewire ports. It also doesn't have PCMCIA card slots to get one of these interfaces or add firewire ports. It does have an express card slot type 2 but I can only get hold of these from the USA and I live in the UK. I also don't know how reliable these will be?
