Even coming from a stihl guy, that echo would be my best value recommendation too. Unless you're willing to pay a huge premium & have a small yard with no heavy duty stuff, then I'd have another.
Btw there are pros & cons with going dealer vs. lowes too. With echo especially, dealers' prices aren't far off, sometimes even less. And long term, buying from a local dealer is better for warranty issues, because you're not having to take it somewhere, asking someone to fix your trimmer who you didn't give your business to in the first place (end of the line). A big box store is better if there is a problem initially. Instead of fixing it, being without your new trimmer for any length of time, you just instantly get a new one. Or if you just don't like it, unforseen design issues, ergonomic incompatibility etc. you won't be stuck with it.
