Is a polisher worth it?

[ProudMarineDad]

Hi guys. I have been restoring some razors over the last 2 years and 99% of them are my own personal razors so I am not in business in any way.
I was considering an electric bench polished like some of you use but was wondering if it is really worth it for my circumstances?
I hate all the sanding and polishing by hand sometimes but a polisher is going to make a mess, etc. so I am wondering what you all think?
Harbor Freight has a dual 6" model for just $39.99 but from the little research I have done that is too fast for our hobby so I don't know.
