For a bit more weight and a bit more room, the Vaude Power Odyssee is very very strong, and can be had for under £300.

This is my tent for wild places, and it works for me as a tent I can get me and all my gubbins inside. And on expedition, I take a lot of gubbins - I am no Caroline McC
But it is a bit heavier than some of the options here.
What I really like about it is the way I can put it up or take it down without fuss in the most wild weather. Peg the tent down, fix the poles to the corners, and then go round the tent clipping one layer of clips at a time. When I reach the height of the guys, guy it out, then continue until it is all done. Taking it down is even easier - just unclip the outer from the poles and it falls into a wee heap, with all the pegs still in place. It is the easiest tent to erect or take down in a storm I have had. The Hilleberg Soulo / Jannu / Allak / Staika / Terra are the same. But more than double the price.
