I know that the brown bed edger is the best there is. The only problem for me is the cost. I am a part timer and don't do much edging. I don't want to rent one because in order to make it cost effective, I would have to do all my lawns in one day and come back days to weeks later to install the mulch. So my questions. How much and how well do the little wonder mantis bed edgers work and what are my other options, I like the "check mark" edge and was wonder how y'all do it with a shovel because it takes me a long time to get it right with a shovel. Thanks in advance.
