Depends on your budget Steven and other factors such as strength and weight. I went throught he same ordeal some time ago and eventually settled on a pair from argos at around ?150 although you can pick them up for around ?15 upwards. The only advice I could give is start from the bottom mate, look at the weight you are prepared to cary around with you then factor in your budget. What I would say is get yourself a cheap and cheerful set and then take into considertation how much you'll use them within a six month period, if the need is reat, then upgrade mae.
