All of my chain saws are or have been Stihl but when it came time to get a string trimmer to use around the farmhouse and surrounding fencing, where the trimming is more weeds than grass,I got a commercial Husqvarna. It had better reviews than any of the Stihl commercial trimmers at that time and the real thing that attracted me was it was lighter in weight that the Stihl machines.

If you do not need a commercial trimmer because you are just doing light grass trimming around the yard then others would have to give advise on those.
