Here's the one I bought off Amazon a couple of years ago. It's a Lezyne Alloy Floor Pump currently $56.67. There are other colors but this one was the least $$$. I don't know what happened to the poster's pump above who stated it leaked. Maybe he was using the adapter. But the standard one is a screw-on for both valve types. It takes an extra minute or so to screw the head on the tube but you will not be wasting any energy with leaking air.
