The choice between electric and gas trimmers and edgers is determined by the size of your lawn. Electric trimmers and edgers are less expensive than gas powered ones; however, you are limited in the area they cover by the length of your extension cord(s) or, in the case of rechargeable edgers and trimmers by the battery life.
The TBE515 Portable Edger (manufactured by Troy Bilt), according to the Galt website is a highly rated gas powered lawn edger priced under $200. Equipped with an ergonomic handle with throttle control and an edging depth of 3 1/2 inches, the 9 inch dual tip steel blade allows for easy lawn trimming. Galt also rated the Troy Bilt Echo PE 200 a great buy that includes a best of the market five-year consumer warranty. A popular model and top seller electric edger is the Black & Decker Edge Hog 2-in-1 Landscape Edger with a three-position blade depth. It also has a 2 1/4 horsepower motor, durable steel blade and adjustable handle.
According to the Ace Hardware website, the top five best selling lawn trimmers are the Yard-Machines Curved Shaft Gas Trimmer, the Black & Decker AFS Electric Trimmer, the Black & Decker Cordless String Trimmer, the Lehr Propane Curved Shaft Detachable String Trimmer and the Lehr Propane Straight Shaft Detachable String Trimmer, all consumer rated at 3 1/2 stars.
