I have a Zefal HPX as well as a Topeak Road Morph. I agree with cyccommute that the Road Morph functions better than the Zefal, and I also agree with the OP that I like the appearance and mounting of a full frame pump. I wish that someone would make a full size frame pump with the functionality of the Road Morph. Most of my bikes have pump pegs, and it is much simpler and cleaner looking to mount a pump under the top tube, so I continue to use the Zefal most of the time. I keep my Road Morph attached to my touring bike because it has a third bottle mount under the downtube where I can attach it. The problem with the Road Morph is that you either have to give up a bottle mount or strap it to your frame with ugly zip ties, unless you have a seat bag or panniers large enough to contain it.
