Silca Pista Plus is the on that I settled on. Retrofitted with a LOOONG hose, Silca analog gauge, Hiro chuck. Near perfection. Smooth as glass action. Accurate high pressure easily obtained. Rebuildable, lifetime of service. All parts are readily sold by Silca or their distributors. I have a supply of hose that equals the factory but can be cut to any length. I sell this with Oetiker clamps if anyone is rebuilding or modifying their Silca pump.
