Camera insurance in the UK - recommendations please

The insurance at http://www.eandl.co.uk/camera-insurance is aimed at pros, and they actually have an option that costs extra for unattended vehicle insurance.

Unfortunately, after taking your money, they then have a get-out clause that renders it worthless in any modern vehicle as quoted in my first post.

If I could find insurance that would actually provide cover under these circumstances, I wouldn't consider it a waste of money. I've spent the last 1.6 years building my collection back up, and it's still full of compromises from what I used to have. Every time I take something out of the bag, I can't help but think about the item it replaced, and how rubbish it is compared to that. The 70-300 just does not compare to the 70-200 f/2.8. The tamron 90 is nice, but nowhere near the Nikon I lost. The Feisol is 'fine' but not a patch on the Gitzo / Markins combo. And all of that is because of a getout clause in my householder insurance policy.
