Ryobi Mower Rating What Brand Of Gas String Trimmer?

What brand of gas string trimmer? - ryobi mower rating

In view of a chain of gas trimmer for my garden (lawn edge to buy a little hard mower deck can not go). I prefer a round 4, it must have a separate container for a single instrument. Does anyone have any recommendations? I went for a Troy-Bilt, but the comments I've seen are mixed? Always on the lookout Husqvarna, Echo, Ryobi.
