Starter Torker unicycle

My 17-year-old son learned to ride a unicycle at camp this year. He has expressed an interest in owning one. I’d like to buy one, but don’t want to spend a lot in case it winds up on the floor next to all the other hobbies he’s asked for.

He’s 5’8", about 100 lbs. I’ve been told a 24" would be a good size for him. I’d like to pay around $75 with shipping. We live in Michigan. Anyone know where I should look? Please/thanks.

Craiglist. Lots of Torker LXs on there.

Even more Torker CX’s on craigslist
