I had used Homelites, Poulan, and McCoullok. Forgot the spelling. I borrowed a friends Stihl MS 290. When I bought a saw that's what I bought, I have had it 9 or 10 years. Starts up and runs great. I use real gas and stihl oil. I leave mine full all the time. Occasionally I get it out and start it and let it run a while when I'm not using it. I usually run the 20 " bar because I don't like bending over. It has been a pleasure to have a good saw that works like one should.
