BootsnAll Travel Community

Here is a link that has a few options:

http://www.BootsnAll.com/insurance.shtml

AllTrip is better for longer trips like round-the-world and working holidays.

Unicard is better for short trips of up to 30 days

GoSure is for UK residents only

I've also included a link to an article on BootsnAll that deals with travel insurance and it has some resources at the bottom which you may find useful as well.

I hope this helps. Remember: it's better to have it and not need it, than need it and not have it.

Cheers,
