I have three B17s that I bought new and I love them, but I took a chance on this one from Nashbar for under $20 on sale. I was surprised at how comfortable it is. Maybe not all day century comfort, but good for fast 20-30 mile rides. It is a little wider and flat on top, so it fits me better than most of the current racy saddles.
