Is the price justified? It is because it is a small run. If Logitech did it, it could have been much cheaper because of economizes of scale, but Logitech doesn't make it. Is it for yourself? That's your choice, try it if you can, and then check your budget.
Personally, I got my current keyboard, a $200+ Topre RealForce after trying a bunch of keyboard in a specialized shop. I didn't look at the price, and unfortunately, I preferred the most expensive. I didn't buy it outright, because I too thought that $200 is way too much for a keyboard, but I came back later, and bought it. I have been using it for 8 years and I see no reason to change, and not once I have regretted my purchase.
