I'm considering buying a straight-shaft Stihl FS 86 trimmer. Can anyone tell me if these are good machines? Not sure if they were robust, or maybe wouldn't be a good choice. I'm going to just be giving it homeowner use, but I'd prefer something that's going to hold up well (and I'd like to go to a straight shaft, from my current curved trimmer). I don't want to simply buy a semi-disposable big-box store machine.
Anything I should check for, to see if it's in good shape? Not sure if there's a compression range to look for (eg- not less than 100 psi), or whether to look for play in the head, something like that. Thank you.
