Got them from the States but through their UK Importer. They got held up in customs for a while, think they took about a month to arrive in total.
http://www.bikehps.com/They all come with red bobbins as standard but I asked for black and they sent me 12 black ones free of charge. Changed them over because I don't like coloured anodising much.
They were horribly expensive I'm afraid. But just sold my house so the way I see it I just swapped a room and a couple of doors and windows for some ace bit of stopping gear. Amy was not too happy with me but I convinced her using the "added safety" argument.
