Different model in what respect? Surely it would be an agency model like any other? Khurusan would need to balance his profits from current sales to the UK and Europe versus reduced profit per item (but on a hopefully larger volume of sales) via an agent.
If the price differential was less then I'd buy his figures - because they look wonderful. And I'm sure there are other people like me.
This is from what I can glean, & from discussion with Nic Robson. Please feel free to correct me Jon (& Nic!) Eureka is a full time business, which casts its own figures on site & IIRC also does some commission casting work for other businesses. There is also a retail shop & there are a number of employees. Nic is fulltime, I'm not sure about the others there.
Khurasan outsources the casting to a number of third parties. Jon puts it all together in his spare time, having a busy full time job as well. Orders are filled out of the stock that he carries. If he runs out of something, he has to order more, no casting to order.
Both models seem to work for their owners & I've got no difficulties in ordering from either, both have always provided me with excellent servce.
