Quechas are lovely, lovely, lovely. We have a Base Second (regular, not XL) with two 3-person Airs to come off the sides as sleeping pods, one for us, one for DCs. Oh, the smugness about turning up in a pitch, waving your tent-filled arms around for a minute or two, then putting the kettle on next to your 'tent' with living room and two sleeping pods.
The modularity makes them really flexible too, so you can arrange the design of that weekend's tent based on the shape and size of the pitch.
We've also just got one of their beach pop-ups, which is equally magic. And have you seen the little rucksacks, that go from being a tiny ball to unfolding into a backpack (bit like the way kagoules used to fold into their own pocket).
