Trial unicycle

I arived in Cape Town a month ago without my uni and I would like to equip me in a cheap trial unicycle 20 or 24 inches. but I can’t buy up to 350 dollars.
Do you know where I can by one in South africa or somewere else in the world with low postal charges?
I am also interested by a used one.
So, if one of you know a uni shop in south africa or want to sell his hold unicycle,please, contact me.
My email adress is ‘’ ‘’.
