The market for Durangos seems to have hit rock bottom - that's from what I've seen as a racer in the Netherlands and Belgium, anyway. I wouldn't be too surprised if the demand for them is so low that they can't justify producing another batch (right away).
To answer your question: It's available outside Europe... OmniModels (eBay), TowerHobbies and Amain.com for example.
Within Europe, you could try RCSpeedshop.nl - his website doesn't list what he has in stock, but don't be put off by it: the owner runs Durango products himself and he always was able to deliver the parts I needed
