Sk camping (nr east grinstead) have started advertising this:
www.skcamping.com/index.php/nordisk-asgard-12-6-m-tent-2013.html
Thought some of you may be interested. Have no idea in the quality or how it compares to the usual sites, but this is at least a shop you can visit and see it. I'm hoping to go there on tues, if I do and they have any, I'll report back.
