Since you're talking about continuous use here, make sure you check the duty
cycle of the compressor. Many of the cheaper ones are <50%. The Ingersoll
Rand T30 that I bought a few years ago has a 100% duty cycle, you can keep
going for as long as you can stand the noise! I'm assuming that the Quincy
is also 100%, not sure about the rest.
