where is a good place to find cheap travel insurance for backpacking through europe?

I tried using that link... But it makes you put one country in for destinations... not that great if you are traveling to several countries

try moneysupermarket.com
This webiste has HEAPS of different companies and you just put in your info and it comes up with a list comparing them (starting with the cheapest...)...ok this is for the UK, but as a Kiwi (New Zealander) I was still able to use it...note that some will not accept people out of the UK, so check that one out.

Try the comparison engine at Squaremouth. You will need to enter a country or area but the text displayed with the question explains that coverage is worldwide whatever your answer is.
