I'm also curious, DUC will be at a trade show I'm planning to attend this weekend, if you have any specific questions you'd like me ask. If anyone else has something to add, I'd love to hear it.
I had heard that the fancy in flight adjustable prop had tended to seize up after fairly low time and there has been a design change to incorporate bearings which seems to have resolved that. That was the version of the prop which was about $10k for the 3 blade prop and actuator/controller.
