Just to chip in... Jason from The Makerspace has confirmed that he will ship international, just not via the googleshop on the site.
For shipping quotes, just hit the contact button with your details and destination country and he'll sort it out for you... and very quickly too!!
Shipping to the UK works out at $13.45, which I think is VERY reasonable. Some US companies really take the rip shipping overseas. I once had a quote of $73 for three ft of macroline, which is a) not heavy b) not bulky and C) would fit into an envelope (a little one at that!!)
