I have one similar to what Buzzy posted and have used it for at least the past 15 years without a problem. I like the double action, it is quick and easy to use. Mine was made in Italy and is of a very high quality with replaceable parts. Not sure a new Chinese knockoff would be near as good. Not convinced that the K-pump is the gold standard though, I prefer to hold the pump down with my feet and use both arms to pump.
