I'm just starting out and have only a few small lawns. I want to stand out from my competition and from what I've seen no one edges. I would like to offer this to my customers and set myself apart. I haven't used and edger before, but I'm pretty handy with my trimmer. Would you recommend a walk behind or a stick edger? I only would have around driveways to worry about. What brands should I be looking at? I dont need top of the line at this point, but dont want crap either. Thanks for the input.
