hmmm, just remember that you always get what you pay for, i had a couple of cheepy headtorches before i bought my Petzl, if your going to be out every weekend in all sorts of weather you need a headtorch taht wont let you down and i have never been let down by mine.
Saying that..........
There is a garage by my that is selling "camping lights" for £2.99, on closer inspection its a ring of 30 white leds powered by 4 AAs, bought one for the brolley, turned it on when it got dark and its like daylight inside your brolley!, £2.99 cant see how you can go wrong
