Alright, so i've got all the equipment i need at the moment, except for a gas powered trimmer. I've got an electric Grass Hog that works fantastic, but i don't want to take the five miles of extension cords to every damn job, you know? So, I need a cheap one that i can get quick. I looked at those Weed Eaters for about 60 bucks they sell at Wal*Mart, but i've gotten many mixed reviews. I also have a Ryobi 425r sitting in my garage, but there's no head on it. I figured that for the price it'd take to get a head for that one, i could just buy a new (but obviously used) one. I need some suggestions please.
