I am going to the Stihl Dealer tomorrow to pick out a new Kombi powerhead a trimmer, and an edger attachment. I am in the Property Preservation business and I am going to be getting some lawns where I will need a brushcutter and a powerhead capable to power it. Now I have 500 even to work with. I am trying to decide between the KM 100 or the KM 130. I don't really know the prices on them. I know I can sub a ryobi attachment if need be to scrape by if I dont have enough. I need some input here guys. Thank you.
