I was just curious if most people prefer to use an edger versus using a trimmer for edging? Advantages/Disadvantages? I'm trying to decide on buying a trimmer, along with an edger attachment, like the Stihl 90R or 100R. I recently used a Stihl 110 Edger at my house and it did a great job. The edge seems so much cleaner than trying to edge with a trimmer, which usually comes out scruffy and to wide. Just wondering if it's worth the extra money for the attachment.
