I recently bought the Milwaukee power head primarily for the pole saw. Only an extra $80 for the brushcutter head as a kit. I use the Stihl around the farm for bigger jobs but the Milwaukee cuts just as well.
Had to mow a small lawn at our place in town, and the lawn mower wouldn't start. Used the Milwaukee . Did the whole lot on less than a full battery charge. I was impressed. Not having the noise is a bonus as well.
