weed eater.....

PLEASE,can someone give advice, I want an industrial type weedy, either petrol or electric, something as near as possible to unbreakable in the wrong hands. I cannot afford to keep byeing Ryobi and it's buddies that are put together in a Chinese toyshop? i cannot help but think of Tooltime Tim, who always makes those rmarks about how he buys something and wants more power, so he fixed it, ugh, ugh i fixed it and put a V8 engine in it, now it really cuts weeds!
where to buy?????
