I have a very old Stihl 025 that has been a good saw. I wouldn't hesitate in buying the MS170 if I was after a little petrol saw. I now have a wood fire at home so am considering buying another 044 as I loved my previous one.
For camping and getting wood for a fire and the Oz pig, I am seriously considering selling the 025 and buying a Stihl Lithium Ion Battery saw. Everything in my camping set up is Diesel, so I find it a pain to carry fuel. I like the idea of the battery saw and have the ability to charge it when out and about. I think it would do for my needs and the odd bit of track clearing.
