I have a small Chinese pump that I've cut the pump head off and replaced it with a double-sided pump head (presta for my tires, Shraeder for my Air Zound) that I bought at Decathlon. The pump was pretty cheap, but it's got a metal body and is pretty durable. It's not as portable as a modern western-style frame pump, but as I've got a large box on my rack that it fits inside, I have no problems carrying it with me wherever I go.

Mountain Morph, is what I use.
