Turns out that there's a UK distributer of HH!
We recently bought a HH deluxe asym (on special from the US store which came with the free HH scout), swapped the normal fly for a hex fly and bought a seperate hex fly for my current hammock.
The $60 was fixed - so we got it for $319 - which is approximately £200. Two hammocks and a hex fly in shipping. Not too bad imho, especially on 48hr delivery.
Arrived on my friends birthday (whom was ordering the HH)
