Amazon offers the Black + Decker 40-volt Max Brushless String Trimmer, model no. LST540, for $99.50 with free shipping. (Target charges the same.) That's tied with our November mention and the lowest price we've seen. (It's the best deal now by $35, although most retailers charge $160 or more.) It features a Powerdrive transmission, automatic feed spool, 13" cutting swath, and an edger function.
