Check out Bravo pumps new Kite/Sup Pump. Iv been using it since the beginning of this year for kiteboarding. They are really nice to use as they have a tall frame and you don't need to bend your knees whilst pumping your kite which makes it quick and easy and takes the load off your back. Its made pumping up my kite really effortless even my bigger kites don't take long.
Definitely worth checking them out.
