I have B17 that I got because it was relatively inexpensive and I liked the look of the leather saddle, rather than being a retro-zealot. Minimum break in time for mine. Break in times tend to vary as the leather between saddles isn't always exactly the same thickness (apparently). It served me well on a three week bike tour and my 20 km daily commutes. I find the dye in the leather does tend to come out a bit, which is a minor pain as mine is racing green. This may not be as much of a problem with the black or natural colours. As well, because it's leather, you need to protect it from heavy rain etc whereas you may not need to do that with a saddle made with all the latest cycling advancements. No regrets buying mine.
