To be honest, if I went to a professional for some airbrush nail art and they got an Argos gadget out to do the job I would probably expect a bad job. I believe that as a professional you have to use professional equipment and products. Just my opinion
Sorry forgot to add a suggestion, you could try ambermist, they are really helpful, the airbrushes are specially made for them by Paasche ( an exceptionaly good make) the compressor is cute and you can then use it for Make up, Tattoos and spray tanning.
