I agree. Just need to find the adapter. Amazon had several hoses with the adapter. Just my luck, I got a hose without the adapter. Regulator should be available at several places here. Any recommendations as to brand?I guess if you can hook directly to the compressor, I just don't see the point in a low capacity air tank. Also, with an air brush you'll want a very specific pressure, which means you'll need a regulator on the tank. Add that to the cost as well.
