Black & Decker 18-Volt Cordless 12-Inch Grasshog String Trimmer/Edger
This trimmer edger does exactly what I need it to do. No messing with gas and funnels and no struggling with long extension cords. Better yet, NO BUMPING or PULLING - it's got an automatic feed system that works great. It's got power enough to cut through those nasty thick thorny weeds that are my scourge. However, the battery life isn't the best ( if you have a huge lawn this probably isn't the trimmer for you) but for my suburban yard it works fine.
the value of this product would be about $70.00.
