I had a conversation about a year ago asking him if he sold the kit and he told me he had sent his masters away to get fixed and they were stolen. I also sent an email 3 days ago so if he is doing them he is keeping quiet about it.
I think I got one of his last ones back in 2014 for under 300. If what 3phase says is true it is truly unfortunate. If I were you I would see what eBay has and scoop one up if you can. There may never be another chance.
If you are interested in paper models; you can get all three canon version, the "David Jones Concept" version and two fan based versions (as well as the cockpit interior and landing gear) for free at www.paperaviation.de.
I have built them all and I have enjoyed them greatly!
