"Made in Japan" meant junk. Eventually it meant well engineered, simple, reliable, tough. Now it has become overly complex computer controlled everything. Similarly anything from long established manufacturers. Returning to the junk phase. All of them.
China is nearing the well engineered, simple, reliable stage. Unfortunately they steal designs and copy things wildly. Reminds me of Japan...except China doesn't give a crap if many of their products are obvious copies, they don't even try to mask it. That seems more honest to me.
I had my least "pro" of my "good" saws out a few days ago. My Echo 590. I hadn't run it since the spring. Predictably, as usual, the tune was off. So I fiddled and farted for a while getting it to run well. As usual. Then it was fine. They are a totally unremarkable saw that cut wood ok, but handle like a cinder block, sound kinda funny, get dirty fast and have lazy throttle response compared to pretty much anything else I have. Boring as hell, but effective. Finicky, imo. I don't know what the hubbub is all about.
Then, the next day I'm back to my blue Supmix. No comparison. It handles like a proper saw, instant throttle response, cuts like a maniac, tunes easily and predictably and runs decently even when the tune is a little off. It's such a nicer saw to run it's shocking, really.
