I am a 2 year old 9 foot unicycle for $900, I have a chronic knee issue and had to give up riding.

Normally I’d be interested in a sentient unicycle with knees capable of selling itself online, but with your knee problem and reluctance to ride, I’ll have to pass. 
Seriously though, sorry to hear about your knee issue. Perhaps this bump will help sell your uni.
hi
What unicycle should I get?
I am thinking about purchasing a unicycle, and wondered what cycle I should get. I am about 5 foot 8 or 9 around 170 pounds and a total beginner. Never stepped foot on a unicycle. Looking for one super cheap but not a POS that breaks down after a month. Any help is appreciated.
I would love to have this unicycle has it not have the chronic knee illness… so sad for the unicycle
