I've been thinking about upgrading trimmers. Right now I use echo 225s, they're really light, sip fuel, dirt cheap and have speed feed heads (a must in my opinion) but a little low on power. I'll be getting redmax 8500s or husqvarna 580s so i'm open to switching trimmer brand to get a better product for my use. Here is what i use a trimmer for, light trimming, lots of edging, and cutting "brush" about once a month. I do not want a 4 mix, I would consider the new still 94r. Price is a large factor, and i'll probably get a big trimmer for those once a month jobs. These trimmers will be only be used for weekly mowing. So what are you're suggestions guys?
