Black & Decker Grass Hog Cordless String Trimmer: I thought for a long time between buying a rechargeable cordless and a gas powered one. I finally pulled the trigger and bought the rechargeable one and it does a wonderful job. There is a guide for edging the grass that (once you get completely used to it) REALLY does a good job. You don't need to bump it, the string feeds automatically. I've had this bad boy for about a year now and am extremely pleased. Battery life is not bad (actually good when you consider that it comes with two batteries).
