Whats half decent?
Bought a shite quick erect jobbie for the family for a June overnight trip and found myself in the midst of a force7 with driving rain.
8 years ago wife goes to buy a tent from Blacks. Finds two apparently identical about the size she wants. One is £60, one is £120, whats the difference she says, 'this one is more waterproof than that one'. The concept of a not waterproof tent was one she was not willing to entertain. So off to specialist supplier, picks a Vaude (£250) and the man says thats a perfect campsite tent, so we got a MacPac (on sale at £300). And she has never regretted it. But then we have used it in extreme places in extreme conditions.
To even have a chance of giving you reasoned advice we would need to have a lot more info about intended use and budget.
Alternatively, you could just post sommat so vague that every man and woman wat has a tent gets to tell you how wonderful it is.
