The 90 will be good for trimming and edging. But trust me the 130 is the way to go. I have both and had the 90 first then got the 130. The 90 will be alittle weak on edging a overgrown sidewalk or curb the first time but would be fine after the first go around. They are both good on fuel and like I said the 130 is only .2lbs more. When I pick up mine I don't know which one I have untill I fire them up. I have the trimmer, edger, blower, saw, and tiller for mine. The next will the the adjustable hedge trimmer and extensions. Hope this helps!
