I'm the kind of person who likes doing things for myself. If I don't know how, I learn. If I'm not physically able, I look for a qualified professional who is.
I've used a chain saw before; cut all the limbs off a large pecan that fell on my house in a storm. I can't see paying someone to do something that I can do myself.
I'm wanting a saw now to cut small stuff around the yard - not trimming 60' hollies, or taking them down... not yet, anyway.
And thinking back, I'm lucky I'm still here and all in one piece - cutting all that wood with No PPE!!!
