Topeak's mounts have changed over the years. This would be another reason to buy from an LBS, you can check the mount in the store (and don't buy if it don't fit).
I bought the Road Morph G at my LBS and mounted the pump on down tube braze-ons. When I needed to mount the extra water bottle cage, I bought the side mount direct from Topeak online, since none of the LBS around here carried it. I do like the look of the pump on the seat stay - I think it would pick up less water and dirt when conditions are wet.
