Where can I find a Judiciar?

So a friend of mine has started collecting the crusading boys and has been looking at various models he likes.

I doubt he will ever play a meta list so I'm not worried about steering him towards models that are better to have, however he has been doing some wiki dives while waiting for various appointments.

He has shown me a Judiciar that he has described as a 'totally badass and cool AF model' and so I've decided I'm going to try and get him one, however I can't find one on troll trader, element, Wayland or gw.

Besides looking through eBay where might I find one?
