Was in Harbor Freight today checking on their ultrasonic cleaners and saw their big ad circular for their day after Thanksgiving sale.
They will be selling their 3gal 100 psi compressor for 39.99. Its currently sold at 59.99.
It may be louder than a hobby compressor, but with the 3 gallon tank once it fills you can spray for a while on the reserve before the motor kicks on again. I have a similar compressor and it is a good multitasker, allowing you to inflate tires & pool toys, use a brad nailer, as well as pressurize my resin casting pot and power my air brush.
