I have a Redmax 8000 which has constantly been in the shop.... ya it has great power will practically break stuff if you blow too close to some things but what good is power when its in the shop all the time. I havent read anything good about the Sthil 600. My 8000 got a new block just a few months ago.... Now it is fowling the plug every couple of hrs using the perfect gas mix. Cant figure out what is going on with it now but im tired of taking it to the shop i am about ready to chunk it. Is there a blower that you guys have really been satisfied with for any length of time.
