A really good friend of mine who does all my work (really good work at that) on my lawn equipment is selling a Stihl BR-400 back back blower. I have used it once before and it runs really good and he wanted me to make an offer based on what others would pay for it. So how much would you guys pay for a used Stihl BR-400 Back Pack blower? Also, the cruise control that holds the throttle is broken to.
