On mine it was some "quilted-top" Japanese saddle, not bad looking but it sure wasn't comfortable! The Pro (mine anyway) had a Japanese copy of a suede Unicanitor...it was only slightly better than the quilt-top.
I would put anything you like on it: comfort tops originality in the saddle dept.!
and I personally would not pay $50 for that seatpost: nothing special at all about it, a $15 Kalloy "LaPrade" style post is every bit as good and they come in practically any size you'll need.
