I found one of the "Weed eater on wheels" at a yard sale 2 years ago. It wasn't running and the guy wanted $10 for it. I offered $5 and brought it home, cleaned the air filter & carb, cleaned re-gapped the plug, put fresh fuel in it , and fired it right up. It's light weight, strings easy to change, and it does a great job.I really don't know what the guys complaining about it giving them a sore back is all about. The hand held units will give you a backache far sooner than this will. As far as the strings breaking, I don't know of any trimmers that won't break the string when you run it up against a fencepost or chainlink fence. They're made to trim grass & weeds, not steel and stone. My wheeled Weedeater has a guard on the left side to keep the string away from such obstacles. Swishers and other large trimmers are way heavier, bulkier, and thus harder to handle and harder on your back. My Weedeater isn't hardly much heavier than the hand held units and I don't have to carry it around.
