Yes, I tried on a couple of Sinns today.
Found the model you listed for about 1800 USD. It looks really good, kinda similar to the Fortis I´d say. (probably just the flieger design though)
It seems that some of the models made for the Japanese market has some weird glass. The catalogue for the flieger states sapphire in the English version, and mineral glass in the Japanese.
I did actually finally find a store that had the b-42 professional flieger model today. It was very nice, but I think the classic flieger model looks better in pictures. I really do think the Ebel seem like a very good value for the money though, and one of the internet stores stated that there was 2 years of manufacturers guarantee. I may very well have misunderstood the chinese signs though.
