Cheap unicycle

I have a cheap 20" unicycle which my sister-in-law has had a go on a few
times and I want to buy her one of her own.

The question is, where do I buy one from? have some 20" learner packs with a ‘Dodger’ uni. These
are £62 + P&P but I do not know how much P&P is!

Any idea if this is worth buying?

If not, any recommendations?

Assuming you’re in mainland UK, postage for that appears to be £8.30. My first unicycle was like that; you might want to consider a better seat if it will get ridden a lot, but it’s a perfectly good unicycle.
