I will soon be looking for an edger, and I don't know which would be better for my purpose, a walk-behind edger or a stick edger. I am thinking that a stick edger would be better since it is cheaper and also if I want to go to a close house I can push my mower and hold my edger. With a walk-behind edger that would be hard. But with a walk-behind edger it might be more stable and create a more crisp edge?
