I contacted the company and Andreas replied very promptly with a shop in the UK which stocks them - Stafford Guitars. I shall place my order today. Yey!
EDIT: order placed. Looking forward to better circulation in my arm when doing long practices! Currently, anything over 2 hrs becomes uncomfortable unless I angle the guitar and so I have to take little breaks (which is not a bad thing in itself, but being forced to take them because of circulation is different) every 20 minutes or so. I'm hoping this will help that.
Negative, I am a meat popsicle.
