If I were starting right now. With nothing and knowing what I now know.. I would buy The 5510 california air tools compressor. (Fairly quiet and big enough to spray anything with an airbrush) it's about 150 bucks on Amazon. And likely an Iwata eclipse hpcs. That's easy to control and very capable it's probably the most popular recomended airbrush there is. I also like my Badger anthem and well I own 6 or seven.. I like all of them. But the eclipse gets the most use from me. You will need an adapter from the compressor to the airbrush some paint and you can start. Eventually a water filter will be needed but it's not a must for water based art. And like all things art... There is always more things to want and all that.. But if start with one good airbrush and a compressor you won't outgrow.
