OK, compressor guru's- what do you think of this compressor? It's at Harbor Freight Tools normally for $99 on sale for $69. It's 1/4 HP, 3 gallon unit. Delivers .7 cfm at 40 psi. I would be using it for airbrushing models and artwork. It'll run a simple brad nailer gun which is important for my usage. It says quiet operation but who knows huh?
