I just bought this one for my cyclocross bike. I know it says 'mens', but I've used both mens and women's Specialized saddles in size 155 (also right for me), and I don't see a difference outside of marketing.

It's just like the one I use on my regular road bike, but a little heavier, and the padding is slightly thicker (still minimal, which is good), hence the lower price. It's $75.00, not cheap, but not outrageous, either.
I've used the Specialized Toupe on my road bike for the last 3 years, now. For me, it's perfect and pain-free. (But read the above links and info before you buy anything, but skip the huge Summary of Saddle Info thread for now).
