Trials uni on eBay

20x4.25" uni on eBay:

it looks alright. i wouldnt buy it prersonally cuz its not very practical but i would ride it if i had one.

My LBS said he sells these for $119, so it’s not such a great price.

Are they any good? It seems a bit cheap to be splined, but is it?

Its not splined, it has a 4.25" tire so I think its similar to the nimbus boomerang. But it also has a rounded crown so I would say that it is worse but I may be wrong. If you are interested in the boomerang I think it would be worth asking the seller what shape the crown is.
