Just set up a Secursus account, Article 6.2 (exclusions) of the Shipping Insurance Conditions is a bit of a bummer though,
"ITEMS SHIPPED THAT ARE SOLD/PURCHASED ON AN ONLINE MARKETPLACE BY INDIVIDUALS. ONLY OFFICIAL BUSINESSES WILL BE COVERED." (Their caps not mine).
Pity as they seemed quite relaxed on the usual "guitar must be packed in a hard case" thing.
