The Greenworks 21212 4 Amp 13 Inch Corded String Trimmer is one of the cheapest weed eaters on the market, but the price belies the performance. This performs way above the price and is perfect for someone with a smaller year wanting a lightweight, budget electric trimmer that will do a great job.
This isn't far off the power of a commercial weed eater, has fantastic cutting power, is so smooth to use, can be easily converted into anyone of 11 other handy yard tools and best of all it comes at a great price.
The Makita XRU02Z 18V LXT String Trimmer has power, a great battery system and a wonderful bump feed head. If you are looking for a battery powered string trimmer this is definitely worth considering. Read my full review for more details.
