Is it worth getting? I know I've heard guys talk about the Stihl Kombi system but not much in the Echo. I was looking at the 266 model which is under the most powerful 280. The 280 is not compatible with the hedge trimmer attachment. Not sure why but that's the next tool I want to get, articulating extended hedge trimmers. The one I was considering was the Echo HCA 266 which is $550. The 266 PAS head is $300 with a 25.4 cc engine. The articulating hedge trimmer head is $280. So it's $30 more but now I have the option of buying separate attachments. I could get the tiller, power pruner, brush cutter, edger. Is it worth it and is it on the same level as the Stihl? All my equipment is ech by the way.
