Your typical $10 mini compressed air regulator is not balanced. Output pressure is affected by input pressure, some units more than others. With a compressor, that is not usually an issue. However, with propane, the pressure of the tank decreases as the tank empties. The result is that you need to mess with your regulator frequently in order to maintain a consistent output pressure and therefore a consistent charge of propane.

Gas regs (other than the little torch head ones) are balanced and will maintain a consistent output pressure as the tank volume decreases. The consensus seems to be that the best model available for this purpose at a reasonable price is the Mr. Heater high pressure regulator, model number F273719, which sells for $18-20 online. You can find them by Googling "Mr. Heater F273719." It is adjustable from 0-60 PSI. On the input side, it has a POL fitting meant to connect directly to OPD valves on full size refillable propane tanks. This fitting must be unscrewed, discarded and replaced with the appropriate size fitting to connect directly to your onboard disposable propane tank.
The Mr. Heater regulator also lacks a guage. You will need to pick up a small cheap guage somewhere and mount it somewhere in the gas line downstream from the reg. Could be mounted in the meter pipe, whatever works for your design. Once you set it, you can forget it.

Propane tanks run at a constant 100-125psi until the liquid propane inside is gone. Only after that does the pressure drop (quickly, I might add).
