vom Eisenherz hit it on the head...people on this forum just don't see the reason to import a dog like that and pay a premium for it.
I'm very happy for OP that they think they got their dog but when you post a couple of youtube videos and people in the know are telling you nothing there is that impressive and actually its less than what they would expect out of a dog that age, one does question what they are getting. Two years ago I would've thought that those videos were so cool, I would've thought that the dog was very well trained and absolutely amazing doing those things. I had also never seen a dog trained in any type of sport or protection. A year later, I know that those videos don't show anything that great, and to make a purchase based off of those kinds of videos gets criticized.
We all have our specialties...we all have what we know and what we're good at. OP is a horse person, if I was in the market for a horse I would go to OP and ask for their advice (I know nothing of horses). I'm an accountant, if someone came to me for tax advice, I would give it to them. So when you come to a dog board, to ask people's opinion on a dog, they're going to give it to you. They will also weigh the purchase price in that criticism.
The dog world is really interesting. We purchase one, we learn from it, we get another one, we learn from it, and so on and so on. OP is happy with the purchase, I think people are just trying to say "hold your horses" a little because it might not be exactly what you want because you don't exactly understand what you're seeing. But OP will get this dog, love it, learn from it, and probably go on to get many more dogs; maybe the same way, maybe a different way.
Not sure if anyone has ever been to a conformation club/show. Those people will tear your dog apart so much worse...and not even for the training but for its genetics and the way it looks! I think the fact that OP is a horse show person they're taking this much better than someone that's never been involved with animals would. I'm sure there have been times when they have looked at a horse and said "YOU PAID WHAT FOR THAT?!?!" It's kind of the same thing going on in this situation...
