There is currently an ad on the TV for a replacement reel that I might
try next. They show it cutting through a piece of plywood (very thin, I
might add) and banging the head against a wire fence.

I've seen that ad, but I always thought half the point of a "string" trimmer was that you didn't have to worry about damaging things while trimming. Why would you want a head that will peel that bark off the base of a tree? To save a few dollars a year on string?

Of course, if you don't have any trees or sheds or sprinklers...maybe it makes sense...
