stihl fs 250
wayyyyy powerful, i bought becuase i can swap gear heads and it can become a broom, mini tiller, edger and ect.
more power iirc then the kombi units and cheaper
it is usually wearing trim line, but I have a blade I use for the heavy stuff, it will take a 2 inch sapling quick, and I have done thicker.
It is a bit heavy, and the vibration can get to you after a bit, but it gets the job done, and I am only using it a for a 30 minutes a weekend on average, and a good 1-2 hours every other weekend, depending on the growth in the back yard.
