you can pay less but they will be flimsy diy ladders, worth spending the money , it will earn you plenty back over the few years you have it, they last a while especially when you start out as you dont use them so much, once your full time they last a few years, so worth spending a few quid, i put decent spikes on mine too, saves the bottoms wearing and find them safer over all
