Thank you all for your feedback. It is reassuring that folks have had success with several brands. I noticed that 3 of you listed EGO, and I made a note of that. Next stop, Lowe's/Home Depot/Ace Hardware! I am going to follow Amanda's suggestion -- try out the ones you all listed for weight, sound, balance. Hopefully, I will have a new weed wacker within a week. Thanks again!
