I got this several years ago but it has hardly been used. It made a nice mess tent for group camping, but it takes up so much space in my car that I just don't see a role for it in my life any more. It is all in excellent condition except for one of the king poles (a plain alloy upright that can be used to extend the door), which got broken when I used it to retrieve something from a tree. It uses Khyam's quick erect system whichreally does get the tent up quickly even if you are on your won, but you then have to spend a few minutes putting pegs in to stop it blowing away.
Yours for £120, collection only, Berkshire/Newbury or possibly Maidenhead.
Here is a link to the currrent model. As far as I can tell the design has not changed much since. Weight is said to be 15 kg and packed size 105*25*25 cm.
