message for sarah, or any one that has info on gutter lances please, we are thinking of buying one, i know sarah bought one sometime ago and i am interested to know if you are happy with it after using it for a while, and also if you have come across any probs with it that you have overcome. what is the maximum height they will go up to. how do you power the jet wash is it petrol or do you have a generator
thanks
Bill
