This spring I'm going to start upgrading all my equipment. I am currently edging using my trimmer and considering buying a stick edger. I have a old craftsman walk-behind edger that was given to me that I can use on overgrown edging. I am using a T22 for trimming and want to upgrade to a T260. Should I upgrade my trimmer first and then get a stick-edger or vice-versa? I do want to get a stick-edger for use on edging and cutting beds (plus it's a dead straight edge) but are the even worth it on sidewalks and driveways when the lawns are cut at 3-4"? Thanks!
