Well, I replaced my Thomson Elite Seat Post with a Biologic Zorin Post Pump. It has the advantage of also being a tire pump and for $45 costs a lot less than most seat posts plus pump. It is a very good pump that will get your tire to pressure faster than the vaunted Topeak Morph and hit 160 psi no problem and is easier to use because you can use both hands to pump. As a one bolt seat post it is not as easy to adjust as the Thomson but this is no big deal because once you get the seat adjusted you usually don't have to mess with it again. For you weight weenies the combined weight of most seat posts plus a pump is more than the Zorin. It is also nice because stowing your pump in the seat tube is a much better solution than in your bike bag or on the frame. Ok, this is not going to impress your high end friends but some times function trumps status.
