I have a 30 year-old "EFCO" (Olympic) - it is a beast of a saw, that is, by today's standards it is heavy and low spead but, it has torque and gets the job done. I've had no problem with parts availability - though I've not had any serious malfunctions or needed repairs in the 6 yers I've owned it. I have probably cut nearly 30 tight cords of Hedge, Black Locust, Ash, Red and White Oak, Silver Maple, Hackberry, Elm and the occasional pine tree with this saw over the past 6 years. I will say, it is not a very good saw for limbing because of the weight. I may replaqce this saw with one that is lighter and my first choice is an EFCO. By way of comparison, my friend has a Husky and when it is working it works REALLY well. It seems to be kind of finiky with the gas one uses however. I hope this helps.
