Amazon offers the DeWalt 20-volt Brushless String Trimmer (no battery), model no. DCST920B, for $99.99 with free shipping. That's $99 less than the best deal we could find for a model with the battery included. (The battery costs over $99 elsewhere, however, making this a deal only for those with compatible DeWalt 20-volt batteries from other tools.) It features a 13" cutting swath and variable trigger with speed control.
