After passing on Stihls for a long time because of the price I finally nailed an old 011AVT on E-bay on the cheap. When it arrived I put on the bar and chain and fired her up. Sounded like a Harley. It was almost orgasmic. I put it in the firewood pile and it was like a hot knife in butter. I was impressed. So now I am thinking about a second Stihl, a bit larger. I read somewhere that the Stihl numbering system had odd numbers for pro saws and even numbers for homeowner models. 028 homeowner, 029 professional version. Or was it the other way around? I have a good memory but it is real short. Those three minutes of good solid memory are like gold! Also wondering which size would be best with a 20" bar? And I have been hearing that the newer Stihls aren't what the older ones were. So maybe back to E-bay for an older saw that doesn't have MS? I am seeking some experienced opinions.
