A couple more quotes, including the cheapest one so far? Both are for 365 days of cycle touring worldwide - Columbus 289.24, Endsleigh 318.24. They are both pretty basic. The Columbus one only has £1m of medical expenses cover, which can sometimes be inadequate for the US. And baggage cover is only £750. Endsleigh has the more typical £5m of medical expenses and £2000 of baggage cover. Columbus has been around for ages and specialises in adventure travel. (They were the only people I could get a quote from when I was fantasising about exploring remote bits of the Sahara on a motorbike.)
