I'm looking into buying a new trimmer and my dealers are saying go with the Stihl because parts are more readily available and order in 24hrs. I have the BR 600 Magnum and like it. I'd be using it for 25 ish lawns a week, which are all relatively large. Echo has a better warranty but the 265 is hard on gas and pollutes a lot more. Don't know which brand to buy. Any advice?
