I am contemplating buying a new string trimmer/weedeater. My current one is a Homelite from the early/mid 1980's which is beginning to be less than reliable and unfortunately if it needs much fixing $$ it makes more sense to start over. I am considering a cordless Ryobi 18v which would use the same li-ion battery as most of my cordless tools, or another gas engine machine. Prices are pretty close , so I am just wondering what insight anyone here can add to the cordless vs. gas choice. I did use a cheaper B&D cordless trimmer my dad had which seemed to work fine when the battery was fully charged.
