I have a gas trimmer and have been considering getting an edging attachment for it. But for the same price as the attachment I can get a complete electric edger. I like the idea of a separate edger as it means I dont have to take the trimmer attachment of my trimmer, put the edger attachment and vice versa each time I mow the yard. However I've never used an electric edger and dont know anyone with one. Has anyone used one ? And would you recommend it ? My only concern is that it wont be powerful enough to do the jobb I guess.
