I like the Edgit but had been told it won't fit my Tanaka trimmer. All I had to do to make it fit was to use the gear box off one of my Echo's (260S), drill one hole for the retaining screw, and it's set and ready to go! Works great! Much lighter than the Echo, as the Tanaka 230 it's on only weighed about 10 lbs without the guard. Here's a pic of it.
