Rolair JC10 Super Quiet 1HP Oil Less 2.5 Gallon Air Compressor

It is a little light on the CFM only about 2.5 at 90 PSI but is only 60 db.
They get the noise down because it basically runs at 1/2 speed.

Never heard anything about the GMC – good or bad. I like Makita stuff – but the MAC2400 is still ~80 dB so not really that quiet.
