Now that I've got a lawnmower to cut the grass myself instead of paying a lawn service company, should I also get a trimmer / edger so my yard looks nice and tidy like it did when the lawn service was doing it ? And if I do, should I get a 2-stroke gas one or cordless electric ? There really isn't all that much trimming or edging to be done, so maybe I won't bother doing it this year and see how bad it looks w/o it.
