The problem with devices like the Stihl is that they are used commercially; that's what they are made for. Used also means worn out. So we really run them almost to the end. So "used very good" is a narrow margin for something like that. The first customer is usually a professional. How good cheaper devices are, I don’t know. With 120 urn holes and some more for stakes and such, a machine like that runs almost every week with us, so we don’t buy anything cheap. A Stihl lasts 10 years here. Karsten
