Check out this combo set featuring Tamiya's excellent Spray-Work HG Trigger-Type airbrush and Spray-Work Revo HG air compressor!
About the compressor: Portable and quiet, this HG Air Compressor from Tamiya is great for home and travel use. Puts out a steady maximum air pressure of 15PSI (pounds per square inch) for smooth paint flow. Has a built-in airbrush holder; runs on AC current only (100V; you will have to find a voltage convertor to use it outside Japan). Very quiet (56db); ideal for apartment use!
About the airbrush: The top model of the Spray-Work HG airbrushes. Comfortable trigger allows for extended periods of use without your finger getting tired. Capable of spraying lines under 1mm thick. The HG Trigger-Type airbrush is a double-action type, which means that the initial spray will emit mostly air to enable fine adjustment of the paint spray volume. Nozzle diameter is 0.3mm.
