I've just gone through a similar exercise as my camera bag has seemed to become rather expensive to replace should the worst happen!
I asked for a quote for £6,000 worth of gear (god it's expensive to take photo's nowadays!!) non-professional use from Towergate - they quoted me £212 + £12.50 policy fee for up to £7,500 worth of kit inc. 45 days foreign travel. :bonk:
Thinking that was rather expensive, I spoke with my home insurance company (Axa), who offer a better level of cover - total cost for an extra £6,000 cover for non-specific personal valuables on a new-for-old basis - £16 for the year! Bargain!!
Home insurance has to be a must when getting quotes.
