I can't even find a lawn care store that has them in stock, they say they are out dated. One would sell me an attachment to a stihl for 150 canadian, John Deere dealer wanted 300 bucks for a john deere model and claimed stihl is a cheaper model. So what about this Idea. IS it ok to edge once a month and the rest of the time just maintain the edge with a String Trimmer? I can find an electric trimmer for 110 black and decker but...it's electric. I can also find this hand edger, it's long stick with a Star and rubber wheel.
