I have been an airbrusher for over 25 years. It all debends on what your going to use it for? I wouldn`t start with the single action. Very limited. It`s better to start out with a dual action. Best place for any airbrush equipment and paints is COAST AIRBRUSH in ANAHIEM,CALIFORNIA USA. They ship world wide and are great to deal with and very informative.
