just spotted this - it's the Argos one - Hike Lite 1 - first time I've tried it myself
(my son's slept in in a couple of times in summer - so I had practice putting it up!)
for sure - £18!
Not sure about the mesh panel just above the head area (drips from condensation?), but that could be easily modified with a fabric patch.
edit - just found this thread about Hike lite mods in my bookmarks
LEKI are pole specialists - making poles is what they do
