I bought this at Home Depot for 79.00 recently.  It works great. Cuts well, has plenty of power.  I was leery of this having the power to cut through the thick tall fescue grass in my yard, but it did it with power to spare.  Also, it doesn't throw the cuttings as far as my old gas edger, which is a plus for clean up.  Being electric, it is cleaner and quieter than its gas counterparts. It leaves a nice edge with a deep groove by the sidewalk, which makes it easy to touch up with a string trimmer once in a while.
