The Topeak Road Morph is getting some bad reviews on durability over at mtbr.com, so I would be careful with that one. The large amount of parts and hinges also pose risks from an engineering point of view.
I'm about to buy a new pump myself and will probably get the Zéfal HPX which appears to be getting only positive reviews, especially regarding durability and ease of reaching high pressures. Construction is simple, so little can go wrong and it's mostly aluminium.
