Bondo, like you, I too have a small yard and tried an electric weedeater (
this one to be exact) and have been pleased with it so far, and I have it going on two years. It's not Li-Ion, and therefore a bit on the heavy side for some (a little modding could put a 4s lipo in there

), but I have more than enough runtime to do the trimming and edging for my yard and then some. It doesn't cut though
really thick weeds like a gas one would (so if you are clearing a field, it won't "cut" it

), but perfect for basic trimming and edging uses.
