String Trimmers - Any commercial Tanaka. These things are so overbuilt they will last until you run it over with a truck or throw it off a cliff. Thier just as beast as Shin if not more. Only reason I can think their not more popular is price (and they use 50.1 mix) but I have two and their worth every penny. I've haven't used a redmax trimmer before and echo I used once and didn't like it comparably. But for hedge trimmers echo would be my top pick for use and price (have 1 HS-150 and another larger echo forget model) not as durable as stihl though. If I wanted to pay $500 I might try a tanaka hedge trimmer heh.
