In reply to leeangell:
I have a Tempest 300, and i have to say, i didnt expect it to be that good for £90 (last year) but it has done surprisingly well, it is not too heavy, and pitches outer first or all in one, which is good if you ever have to put it up in the rain.
It stood up to 12 hours of continual heavy rain when i walked hadrians wall in summer. It also stood upto the wind well, as long as it is pitched with the back into the wind.
The porch is a decent size and has a clever pole that doesnt touch the ground at anypoint but makes the porch a good bit bigger.
But, the pegs are pretty rubbish, so get a few decent ones if you plan to use it in windy conditions.
