Seems like corded would be longer lasting than a battery operated one. I did see that there are some that can do both and that would be nice if it actually worked well. It would also be nice if the blades could be replaced. Also need guards for different sizes. The last posts I could find were from about ten years ago and I'm afraid that the build quality has gone down on the recommendations from then. Budget would maybe be up to $60 at this moment.
