I run Stihl FS 85RT. The trimmer is just a little over a year old and it was pretty decent, but since last august, I've been having problems with it. My trimmer is really moody, especially in hot weather. I used to think the hot weather helped things because there was a time when it would start on 2 pulls. Now, all it does is die if you flip it up for edging for a long period of time, then it floods, and then you can't get it started again. More importantly, it takes about 5 pulls to start and with 95-100 degree weather here, I'm not really into yanking my brains out trying to get it started when I'm tired and want to go home, plus it makes you look like and ----- when people see you're having equipment troubles. The verdict : Buy a Redmax or Shindaiwa. I've just been through so much BS with the thing I don't want anyone else to go through it. I'd sell it, but my dealer is great and I wouldn't get much for it, plus I have the edger attachment for it as well. Whenever I break down, my Stihl dealer takes care of me right away. I'd say go with whatever you can get a good dealer relationship with.
