I thought about the Dr. Power trimmers. There's a lot of manufacturers that make a wheeled string trimmer that's very similar but much less costly. But none of them offer a circular cutting blade for them.

I've been reading up on all of them and the best I can figure is,..it's a liability issue. An exposed circular blade on a wheeled carriage must make the company lawyers nervous.

You know some idiot is going to run up and cut their kid's leg off with one of them eventually.
