Wood Splitting Christmas Gift

Hello! My Dad is getting older and I don't want him to have to split wood using an axe. I wanted to see if anyone had any recommendations for possible gifts that might make his life easier (and his back hurt less).

Here are a few I found. Does anyone have any insight on any of these?

If I could afford an electric splitter I'd totally do it, but I'm looking for a few more affordable options first. Thank you for your help!
