I was in the same boat since the past month and seeing this post I was finally tempted to register on the forum and post a reply!!
I note that Scout has suggested a Firewire to USB converter, and it definitely isn't the cheapest solution!
I'm currently using a Firewire to PCMCIA Cardbus adapter without any issues and the best parts are that they're way cheaper and you can have multiple Firewire ports on the Laptop. This is great as you can connect the camcorder and an external hard drive to the Firewire ports. You soon find that you're investing in software, external hard drives, books and lots of time to get half decent results!!
Noting that you're location is in the UK, I've pulled up this link on Amazon
http://www.amazon.co.uk/Firewire-Cardbu ... B000MS96X2I hope I've got the link right! As you can see you get multiple ports at a fraction of the Firewire to USB converter. This should give you a start and you can try and see if this product is available in your favourite brands.
Hope this helps.
