Best weed eater

So my dad has a business where we do a lot of clean up around industrial sites. Yesterday one of the weed eaters gave it up. It was a stihl 108 and the guy we took it to said the coil was out not bad for a 20 year old tool! The salesman at the local tractor dealership suggested a myamura. Said it came with a 5 year warranty and recommend it over the husqvarna they sell. Have y’all ever heard of this brand? I haven’t and I would go with another stihl but the local dealer does not provide good service. So what would y’all recommend?
