My local dealer has always been an exclusive Echo dealer, so that is all I own. I have always been happy with the ones I have owned. Powerful and lightweight. Well, last week they picked up the Stihl line. I went into the shop to check it out and they offered me the FS 100 RX Trimmer as a demo to try out and let them know what I thought. I used it for one day and my crew for 3 days. I was really impressed. It was actually lighter than all my Echo trimmers and a lot more powerful. Engine seemed to be a lot quieter also. I ran this thing through some pretty thick stuff and it would not bog down at all. My crew loved it and asked if I would trade all the Echo's in on the Stihl. While I cannot justify doing that price wise, I will own one in the future. Does anyone else own this particular model? If so, how well do you like it and how is the durability?
