Personally, I would have stuck with Echo. I moved away from Stihl products decades ago when they began to price themselves out of the market. Back then, Echo products were vastly underrated and relatively cheap compare to Stihl.
Now all I buy is Echo.
Since 2007 I've bought Echo Shred N' Vac, two trimmers and a chainsaw. Everything is over ten years old, still running strong with NO work or replacement parts of any kind so far.
Have to say though, the Shred N' Vac is starting to get cantankerous. Still runs OK but slows down when hot. I think the electrics might be starting to go.
The Echo trimmers are nice and light compared to my Stihl trimmer/brush cutter. I seldom use it anymore. it's 34 years old and I've done nothing to it other than clean the carb. Great machine other than costing three times the price of the Echos that replaced it. It's getting hard to start and probably in need of fuel line replacement.
