I have both Jaco and Joes Racing gauges both 0-60psi. Both showed the same 33psi in a random tire test, so you can't go wrong with either in terms of accuracy. The Joe hose and fitting is approximately 19 inches long and the Jaco is 15 inches long. The Jaco dial is slightly smaller, but both are legible. Both appear to be well-made reliable sensors. In my opinion Jaco has 3 decisive advantages. It costs about $6 less, has rotary connectors on both the dial end and hose clamp end, and holds the pressure reading until you release it by pressing the deflation button. If I were to buy another one at this point, I would buy another Jaco, if only because you can rotate both cartridge and caliber independently.
