Is that the New Forest camp? You'll both love it.
Sorry, I don't have a tent for sale but I will say this ... if you already have sufficient camping gear then you could do a lot worse than holding on to your cash till after your first camp where you will be able to check out a whole load of different shapes & sizes of tentage.
Some say that tent-envy is a rocky road, but correctly harnessed can be a powerful tool.
FWIW: No one ever got fired for recommending Vango
