Beginner Unicycle Sun 20in?

What I’m looking for is a just a basic beginners unicycle. I am looking for one I can possibly juggle on since once I learn how to ride that will be its main function, and also one that will be $100 or under. Does anyone have any recommendations for a unicycle on the cheaper side that would fit these two things?
I was thinking of just a basic Sun 20in kind of like the one here. So if you could I’d like some help on the matter or a critique of the Sun 20… Thanks
