Was at my Stihl dealer last week and I was questioning him about the BR 600, Etc. He had been selling it for $479.00 but told me it was on sale currently for $429.00. I thought, Thats a super sales price and I bought one. It is very quiet and the padding on the blower against your back, Is extremely comfortable. I used it one time soon after I got home and am very pleased. I even did the solid red brick test out on the road and it blew the brick as fast as I could chase after it! I asked my dealer if I had to run it the first couple of tanks (gas) at half throttle and he said no. I had thought I had previous read elsewhere on the forum about half throttle to break it in and thats why I asked. Overall, It looks to be a great backback blower and I couldnt beat that price any ole day either!
