I have been running Stihl about a year and a half and have not had any real problems. I also have a Husquavarna that has been ok. I an ready to buy another trimmer (a larger model) and have located a RedMax dealer close to me. The shop seemed to be very heplful. What model would you guys recommend me purchase. I want something that will cut really dense weeds and grass. Mostly for heavier stuff so mu smaller Stihl FS80doesn't wear out faster.
