Anyone have any experience with them? They seem to be well reviewed but hard to come by in the U.S. There is a 931 on ebay right now

And a used 853

The 931 is especially interesting just because you don't see many stainless frames on the road and seems like a good alternative to Ti (which I've been considering for my next build)
