I have seen and owned Silca pumps with other than the Campy metal heads (the kind with the two prongs on the end) and they all sucked major rocks. Without exception. Only the Campy metal heads are worth a shiznit.
The Zefal HP's work better than even the Campy-headed Silcas, though, and are better at fending off the occasional obnoxious dog.
