I like em, although you don't want to be in one on top of a mountain in a storm. My old one was from Tesco £14.99 a few years ago, it lasted almost 6000 miles in the back of the 80, although on the last trip I had to stick socks in the holes and it filled with water. Also mine was not quite long enough. As Dave said great to put up just throw it where you want to sleep and put your bag in it to keep it on the ground so no pegging out required. Putting it away is more of a struggle with a real knack that I just couldn't do, so I just shoved it in the back half folded, hence all the holes!
