I bought a SKS pump a few years back and it's quite different from the $10 pumps I see at Wally World. Although it is made of metal like the less expensive pumps, the SKS feels more stout in comparison. The base on the SKS was a heavy chunk of cast metal with integrated air gauge while the less expensive pump used some stamped steel. Every part of the pump is modular and can be replaced; for example the hose and nozzle assembly is threaded on to the base of the pump where the $10 pump has the hose crimped on. SKS also provides lifetime warranty on their product.
