Stihl (pun intended) running a 1982 Pro Mac 625 ($250)with a 24 inch bar and a yard sale same age Mac 600 (20 inch bar)that cost $3.00 at a yard sale. They only get about 12 hours of run time a year for firewood, but they can hang in there with a Stihl 460 Magnum (32" bar)that only comes out if I get into big wood.
Keep those chains sharp and near anything can fly through the wood.
