A quiet compressor?

That eastwood compressor may be quiet but the cfm is rather low. They used the old trick at showing cfm @ 90psi. 12.7@90 is not very good. It would not be good for sandblasting or air hungry DA sanders.
In the end it all boils down to budget and what kind of work your doing with it.
When it comes to noise, the 1725 motor is what you want. Avoid oil-less compressors at all costs, they are the noisiest of them all.
