I have a Specialized Oasis saddle that I bought in 1999 based on a reccomendation in Mens Health Magazine. It was suppose to be orthepedically designed. The front narrow part is still intact but it has been hollowed out. Also, the rear extents out wider so more weight is on the bones. I like it very much. Specialized no longer makes the Oasis but they make a new generation one. There are also generic knock offs of this that I have seen at Nashbar.
I say more about this and posted some links in the following thread.
