Cyclone yasi has inspired me to do a course and buy my own chainsaw. A local person told me she uses an echo husqvarna. My father agreed that husqvarna is a good brand but on the website i don't see any echo. How do I figure out what size machine to buy? I've got big trees and little trees. We've got a hectare but don't actually need to clear it. Has anyone done a course? What did you think of it? I"ve found one for $250 for three modules though i can't remember what the modules are called. I told the guy i've got trees to cut down.
