I agree, I wouldn't touch one personally, I need my stuff to be very reliable. Things like pistons, rings, cylinders, fuel tanks, fuel caps, carbs, fuel lines, kill switches, recoil housings, chain brake handles are all weak points that can fail at any time without notice. I know a guy that bought a container full of the 660 clones for 80 dollars per powerhead and those were the common problems with them. The quality control is non existent and it is common to find hardware that is not torqued down and fasteners that should have loctite don't. I would recommend a good used saw to most people before them. It just seemed to be a gamble with them, some ran ok and some were just plain junk. I would rather buy once and cry once then have to buy 2 saws.
