I have the MS211 with the 16" bar, brilliant machine.
I need a decent machine because my garden is around 2 acres of what could be classed as woodland.
I first bought a cheap £50 petrol chainsaw, complete waste of money.
If you need a chainsaw, buy the best you can afford. Usually Stihl or Husqvarna.
Just remember, the longer the bar, the more teeth to sharpen, and they need frequent sharpening.
