I much prefer Line-X over the current Rhino. Rhino used to be the best around but based on my last one their quality has dropped off. It was much easier to cut than previous versions, and easier than a Line-X.
Traffic from INGO can buy a Stihl FS55R at Midway Power for $190. It is easily out best selling residential trimmer, and most everyone who upgrades from a curved shaft is happy they did.
