hi
I’m looking for a 24in freestyle uni preferably between $150 to $250. If uknow of any good quality ones pls tell me about them.
ps. preferably a nimbus! 
You might be a better response if you post here with a title similar to
[Wanted] 24" Freestyle
Then include where you live so you aren’t offered a unicycle from the UK if you are in Brazil (I have no idea where you are)
edit:
I just re-read your post, what are you asking? It sounds to me like you are looking for a 24” Nimbus Freestyle uni for $150-$250
That is how much they are new from UDC. (they are listed under Cruiser (24-inch))
Are you waiting for people to tell you that it is a good unicycle?
