Personally.... I would get something like these WTB KOM i23 rims , some mid-level Shimano or Novatec hubs, and then get them hand-built with either DT Comp or Sapim race double butted spokes.
I think @Howard or one of the other CX crowd should know where to get hold of Novatec hubs.
I have those I23s on my Habit.
Novatecs can be had from Superstar for £100ish the pair.
Trouble is, by the time you've built them up and sourced some non-shit rubber for them, you've spent more than the £330 or so that CRC want for those blingy Mavic XC wheels, which come with UST tyres.
and the bonus of not ending up with a yellow wheelset

plenty of folks use UST rims with whatever rubber they can find. It's the rim that makes things super easy; pair it with a UST tyre and it's a no-brainer. But I guess you already know that, right?
