Last trip to Europe I got some insurance through allcleartravel.co.uk because they asked questions about, and therefore covered, my Type 1 Diabetes and anaphylaxis. I looked at a few others, but they never asked about those conditions, which put me off them. If you have health issues (hope you don't) have a look at them. Otherwise, there are no doubt cheaper options around and if nothing else, make sure you have one of the EHIC cards.
