What kind of hedge trimmer? I have been wanting to get one and want to not get a corded one, but don't figure I need a commercial sized gas powered unit either.
Cordless battery powered seems the way to go, just don't want to wase $$ on a unit that can't do the job.
As far as weed wackers, I have a gas powered one that is great. Had a corded one and hated it. I like that this one has power to hack into some pretty thick weeds. Of course if I got to them earlier, they wouldn't be so tall and thick to begin with.
